I know there have been a few threads on this topic over the last year or
so - based on recommendation requests.

Rather than ask for recommendations per se, I would just like to know
what you folks think is important for a cordless screwdriver (_ drill if
possible) to meet my needs.

These needs are quite modest. I have a small B&D unit that is OK for
small jobs - but it is low in torque and today wasn't up to putting 30mm
screws into the barge boards for my new guttering. I don't usually ever
put in more that 20-30 screws in a session or drill more that a few 6mm
holes in brick. i.e. modest DIY activities - shelves, guttering, IKEA
furniture, etc.

So don't want to spend a fortune but need some advice what to go for, so..

What voltage should I look out for and is more always better ?
What's a minimum torque you would choose?
Would you suggest variable torque settings ?
What's an acceptable charge time?
Are there difference in battery type/performance?
Over what weight would you say it becomes tiresome?
Would you go for a drill/driver combo?
Anything else to look out for?

Thanks for any pointers
