After pricing out replacement batteries and chargers for my Milwaukie 18v, I decided to buy a cheapy Craftsmen set which included the 18 Volt drill, 2 batteries, charger, and a right angle drill which is powerful enough for residential old work stud boring. Grand total, $99.00 plus tax. So far the only complaint I have is the chuck loosens up quite often, other than that, it's suitable and the right angle cordless comes in handy.
