A couple of questions that I thought I'd ask:

The first is as per the subject line: What would I need to construct a PSU
for my 18 volt cordless tools. My batteries just will not keep up. ( I was
thinking only of a transformer and a full wave rectifier, and wondered if I
needed something special to allow the variable speed function to work)

The second is that I found the link below on:
Ernie Leimkuhler and Stagesmith's Massive Metal Links List, and it's got new
dewalt 18 volt batteries listed at two for $108.99. That seems pretty good
for an over the counter sale but I wondered if there's any better price out
there??
