Upload & Sell: On
I actually have bought lenses from that seller, they were exactly what advertised and shipping was somewhat fast. I'm not sure about cameras, seeing as you guys are a bit anal about what is canon authorized and what is not, so take my experience with a pinch of salt.
Just remember that the Chinese new year is really close, so you might get some delays, or maybe you could get a better price after the holidays.
I buy everything used, I could care less about warranty.
I'll hold off until the new 7d comes out and decide then.
