Ideally want to spend much more than £50 if possible
I have the bosch blue 10.8v impact driver and its a noisy waste of time, don't bother. The 10.8v screwdriver is much better as its a lot quiter for a start. If you get an impact driver don't mess about with anything less than 18v
but 18v is much better at driving 4" screws through 2"x4" tho
This was supposed to simplify choice! I've got a potential offer of nearly new second hand Hitiachi li-ion one, will see how that specs up.Thanks all for advice.
If you want to prevent the ends of your timber splitting, and most people do as you're taking away from the integrity of the wood, then you blunt your screws, the sharper the worst, and nail your studding together, so much cheaper .........
