I've ordered from
these guys in the past. They ship direct from China. Shipping is very cheap (US Mail). Very cheaply priced stuff, but for some of it, you get what you pay for. I have sort of a mixed review, but overall I'd definitely recommend buying from them.
I bought about $50 worth of stuff. I have a Motorola Startac. I bought a battery, a desktop charger (charges both the phone and an extra battery simultaneously), an antenna, and the "electromagnetic field blocker" or whatever it is. I'm pretty happy with the battery and the charger (obviously the bulk of my purchase dollar-wise) -- they both work fine, and the battery seems to last as long as my original battery (~2-3 days with light use). The $0.25 antenna was a plastic piece of crap, and who knows if that EM blocker stuff is a bunch of hooey anyway.
But as I said, the majority of my order works perfectly, and God knows that the $25 I paid for the battery was a lot less than I would have paid for a real Motorola-branded battery. Looks like they're even cheaper now... I might have to order again
edit: oh yeah, I actually bought a car charger too. I'm not sure if it works, though -- either that, or my car's cigarette lighter is broken. I actually can't tell

but hey, it was $6 or something.
