FWIW, as someone who has purchased many items from both, I'd go with the "name brands" like Dengfu, HongFu, XM Iplay, etc. A company that has a reputation of sorts, and can be tarnished by your poor reviews if something goes south, is definitely better to work with than the eBay guys. That is, unless you're buying from those places via eBay, in which case it's a wash.
