I have also killed a new die grinder from a big company in less than a half year.
So i would recommend a cheap drill or you spend big money on a professionell flexible shaft machine. I did it, and i dont regret my decission till now...

Actually, I agree. Electric drills burn up quickly. I was lucky enough to trade some polishing for a 1-1/4" diameter flex shaft, but it's not economical to buy one unless you do it professionally. The $20 air die grinders work fine for high speeds but you need a good compressor. I got a decent electric die grinder at Harbor Freight and it is holding up very well - in fact it's my main machine for initial steps. With a motor speed control (such as sold for routers), I could use my die grinder for polishing as well, but I have the flex shaft for that.
