ORIGINAL: Mode One
I still use and love my "Egg Beater" drill! I think they are still available. I have a Black & Decker cordless drill that is all but shot because the battery packs (which are still available) cost almost as much as a new drill motor! I just can bring myself to throw the danged thing away and buy a new one. They make the battery pack so you have to break it to get at, and replace the batteries. Right now, I think I'm going to break into them and see if i can replace the cells! If I can't fix, I'm really not out anything.
Have you looked on e-bay for replacement packs? I found some for my Skill drill that were new and about half the price they were at the local Home Depot.
