Can somebody from expirience suggest me a quality tool, with separate power supply.
Like this http://www.dealextreme.com/p/professional-electric-screwdriver-with-power-adapter-set- but higher quality and easily available tips?

I would ask the following: What kind of torque range do you need? What kind (if any) of torque control do you need? What kind of switch do you want? (the one you linked to has a small toggle up high - doesn't look convenient).

I would be happy with torque setting from 0.5 to 5.0 or 7.0 kgf-cm, i would like it not to use clutch but full off when set torque is reached. The switch should be a push to start but if there is not any other option i will settle with lever trigger function also. The one from the link is crap, its just to better explain about what i mean
Altrough i never used pust to start function so i dont know can the screws be damaged easily from the screw bit not seating properly. I like this one, but im not even thinking to go in that price range http://www.expressassembly.com/catalog/proddetail.php?prod=EA-412P

Don't bother with one of them old fashioned mechanical screwdrivers get one like Dr Who's, Sonic screwdrivers are the way to go.

I had a Panasonic branded cordless screwdriver for many years, I used it daily to assemble and repair computers. I can thoughly recommend them. They are a bit expensive, but like any quality tool, worth it in the end. I have tried heaps of 'el cheapo' 'one hung low' ones in the past, rubbish compared to the Panasonic.

Looks nice, i allready put a bid on it. Not a 220 VAC but that can be solved . However i dont plan to bid alot on this item since it looks like seriously abused

I didn't make a comparative study of it but I've used Kolver tools and they seem pretty good.

Mix of both, more second that first. The usually drill has becomed too heavy, battery screwdriwer too weak, no torque adjustment

Wow! the power of suggestion. I had no intentions of buying a power screwdriver even though I could really use one for my home business. So I figure I would look to see whats out there just to try to help a fellow forum member. But after looking I could not resist a Home Depot visit this morning. I checked out every brand of pistol driver they had and the Milwaukee was still the winner. So thanks hacklordsniper for costing me $99.00 this morning

Dear Hacklordsniper"
--From some of the responses you are getting, it appears that you failed to make clear that, your goal is to assemble electronic projects, and not to hang drywall. I get these kinds of responses also. If you wanted a doorbell, they would tell you "Just have them knock".

Hello, you made a good point.
Im searching for industrial screwdriver for assembling products and use it for personal projects and various teardows. I think i will go with express assembly, im little disapointed that i will have to spend a 600 $ on it. I will go for the brushless model and lever start. I start to think "push to start" system is only useful on production enviroment for assembly and if you always use the same bit and exactly one type of screw

This is a bit off the wall.
If you are not wanting to spend big money on a ready made solution, how about hack a cheaper commercial pistol shaped driver.
The handle usually contains the motor controller so remove the controller and handle mount on a bungee or similar to relieve the holding strain. The gearbox and motors are pretty strong and reliable even on budget drivers.
Hack a controller, with a variable averaging current consumption detection to latch off the power as a torque control.
Add a momentary action start switch.
This just off the top of my head and would need some work but I would think it could be cheap and cost effective.
Probably would not meet heath and safety requirements in the UK if used in industry but thats a different question.

Before i buy a new one im still looking at ebay for used ones. Alot of great screwderivers appear (some without power supply, some with) but at very good price. However all of them look so beaten up, abused and poor. Im just waiting to maybe "catch" something.

I was thinking along the same lines. But one problem is the diameter of the motor/gearbox is rather large compared to the typical power screwdriver making the ergonomics less than Ideal. The electronic
only (no clutch) torque control I think needs to be fairly sophisticated to account for the inertia of the motor armature and gearbox continuing to dissipate their inertial energy after all current is removed especially at the rpm typical driver speed. Think about a screw into a nut at rpm. It has virtually no drag torque until the head of the screw hits the nut face. Even if you de-energized the motor at the exact instant the screw seated against the nut the inertia of the motor/gearbox would have to be dissipated. My hunch is that even the models that turn off after reaching the set torque have a clutch for this reason.

100 rpm is the speed of this driver. if you had a 0-80 screw 1/4" long it would take 12 seconds to remove it. I think you might fall asleep waiting for the screw to come out. That is way slower than you normally spin a screwdriver by hand. Even the 500 rpm of the Milwaukee driver I mentioned earlier in this post is almost too slow. I think you would be very disappointed.
