I have three TP-Link 200Mbps ones (two of which are pass-through) and they've been fantastic since I got them in December. Not had a single problem with them, and setting up was as simple as it gets; connected cables to adapters, plugged them in, turned them on and that was that. No set-up wizards, no pressing buttons to pair them. Even with one of them connected to a switch which feeds my Sky box, PS3, 360 and TV, I've had no bother.
The only thing that lets the TP-Link ones down is the software, they seem to do a different version of the software for each different adapter and none of the versions are very good. That said, you don't need the software at all anyway, useful for seeing speed stats but that's it.
