If it were me, I would phone up the places listed under "Tools - Repairs" in your yellow pages phone directory.

The people that work at tool repair shops will know which Chinese cordless drills are junk and which ones are actually pretty good. And, they'll know which ones are made by the same Chinese companies that make Bosch or Milwaukee cordless drills (for example) cuz they use the same parts as Bosch or Milwaulkee drills.
