Ok, after looking at some of these I realized that the majority of them are HTIB's so I'm good to go with that.
To answer your questions m_vanmeter:
Room size is I believe 18x15 or something like that...pretty good size room.
My media room is designed with 7.1 already wired, so I would like to mount the speakers where they are setup. I'll have 2 up front, 2 sides, and 2 rear and of course the center speaker will be on top of the TV stand below the mounted TV. The stand will hold all my AV gear along with my PS3 and DVR. Yes, my PS3 Slim will be my BD player as well.
I also know that the pre-set speaker holes are covered with wall plates and I've seen some setups from the same builder that would have the speaker inside the hole with an outer speaker cover with breathing holes setup, so you really can't see the speaker. If that's an option for me once I take off the plates I wouldn't mind having speakers to fit in-wall vs. on a mount coming out of the hole. Either way is fine I guess, but I'll know for sure once I see behind the wall plates.
I don't want towers or speakers on my TV stand...they will all be mounted on the walls.
Also, I did like the Onkyo S6200...a good middle ground compared to the S5200 and S7200 which has the tallboys which I don't want. So far, out of all the ones I've read up on (i.e. - specs, reviews, etc.) I'm leaning towards the Onkyo S6200.
