I've reapired way too many cameras bought from fleabay n can tell you they are mostly junk dealers, not professional sellers like KEH.

KEH equipment is generally better than it's ratings and if you think it is not they will exchange it no questions asked. KEH also has a great return policy without any arguments as you would definately get from Adoroma n B&H, seen too many bad experiances with those guys.

B&H is a great place to shop for new stuff but their used equipment seems more like referbished garbage finds.
