Considering going in-wall over freestanding-input

We're considering going in wall for home theatre. Used to good floor standing speakers. Anyone done this?? How much comprimise is it? Speaker recommendations??And what about wiring? I ssume all those expensive cables should be no less important.

Try Thiel speakers, they have in wall, out of wall, subs, floor sanding, and mini-monitor solutions.
I just did this myself, and choose the new B&W Signature 7NT in wall. I originally planned to install both side and rear speakers but remained with traditional Dolby 5.1 configuration.

There are other in wall that do a great job as well, especially if you are a two channel guy (like me) and just want great surround with minimal interference with the stereo.
