<< Any recommendations on voltage and brand? >>
Look up the Consumer Report article from a while back. The 18V Milwaukee and
DeWalt were rated well then. There are some lower voltage recommendations, too,
which, sorry, I can't recall. Based on that I bought the Milwaukee (on eBay!)
and it has done quite well. I don't find the added heft at all a disadvantage,
but YMMV. Good luck shopping.
