Chargers and docks are probably fine, but I'd stay away from the cheap batteries -- especially the ones from overseas.

Case in point: Friend of mine bought a 1600mAh battery for his phone (not a Pre) on eBay from a Hong Kong retailer. He had it for a couple of weeks and it went bad and bulged out.

Since it broke open the battery casing when it bulged, he took it apart to possibly see what went wrong with it. The outside said it was a 1600mAh, but inside was a 750mAh battery. He emailed the retailer, telling him what he found, and the guy just said, "I'll refund your money".

I'm not saying everything you buy from overseas retailers is going to be like that, but if it's too cheap to be true, it probably is.
