For about a $100 you can get the dewalt rebuilt, or at least you use to could.
I got a 18v dewalt drill that I bought in Chicago in about 2003 or so. Was doing service tech work at the time and used it most every day. After about 3 years it started getting weak, so I had it rebuilt and since I didn't have that job anymore and don't use it nearly as much, it's still going strong.
Also, I buy rebuilt batteries for $40 that are way better than the factory new batteries.
