Home Theater - $5000 budget

[Purplegrasshopper]

Hell everyone,

I've been saving money, and now I'm finally ready to make the plunge. I have a $5000 budget for my entire home theater - TV, audio package, and Blu Ray player.

• Blue Ray player: I've already decided on the PS3 for my Blu Ray player, so that's set. Cost is $399.
• TV: As far as my TV, I want at least 52 inches. I'm leaning towards LCD, since the room will have lots of light from windows and other sources. I was thinking something like the Sony KDL-52W4100???
• Sound system: Here's where I need the most help. I figure if I spend around $2000-$2500 on the TV, I will have around $2000-$2500 to spend on the speakers, receiver, sub, and cables. I'm leaning towards 7.1 if I can afford it; if not, I can settle for 5.1. I'd like to get in-wall speakers if I can, but from what I've read, the quality just isn't there with in-wall speakers.

Thanks in advance for all of your help!
