Chinese brake drum issue???? HELP!

I just replaced the rotors on my Grand Am...they were 8 months old. I had problems with them from the beginning and it finally got so bad I had to do something. The inside face on both had a track of "bubbles" that looked like it had been a casting mistake. They would heat up and pulse. MADE IN CHINA! I spent yesterday re-building them and now it seems ok. The local shop tells me it's a crap shoot, either you get a good set or not. Now for the best part, replacement exhaust manifolds out of China are even worse. Vic, the guy at the shop, says it's more common then the rotors. I don't know where to get good rotors and drums anymore. Wasn't it a great idea to off shore all our industry??
