Inexpensive USB bluetooth adapters?

[SoundWagon]

I picked up a $.99 bluetooth adapter from china, and have tried it in a mac and 2 pc's and the iPhone 4 can see it, but the iPhone will eventually say "not compatible with this device".
I have an older iogear bt adapter that works fine, but costs near $20, and I need 3 of them.

So, what's cheap and works well?
