I bought an 18V REMAN DeWalt drill over 10 years ago. Wore out the old style batteries. I added a recip saw w LiIon battery and charger, then a Jig saw, and a circular saw, and impact wrench, a cut-off grinder, and a snake light, all 18V. The drill and saws have built fences, decks and what not. If I can keep a LiIon battery on a charger, I'd rather have these tools than any other battery brand or plug in made. I drilled over a hundred holes with the over 10 year old drill today.
best wishes,
Les
