I sometimes have aspirations of getting into building a great setup, but thankfully I've gotten to a point of "good enough for me". Thank God, because I'm already modding the truck, fiddling with car audio, upgrading computers, tools, outdoor gear... sigh...
Anyway, I'm just rolling with a 52" Panasonic Plasma, Logitech Z5500, aging LG BD370 (hey, it was the first thing out that had Netflix without having to pay for Playstation), and a Logitech Harmony remote to make things easy. Nothing special, but it keeps me happy enough.
Also thought it would be fun to post up my ghetto fab theater from college. BenQ projector, no-name speakers that my roommate "bought out of a van in a parking lot", and an original xbox. The screen is just a bunch of 20' tall drywall sheets. Seating is a bunch of Goodwill couches (we eventually built stadium seating for the couches).
Only place in town where the screen was equal to the movie theater and we could serve any beverage you please!
