I want a semi decent setup for my reasonably large lounge at home. I don't need the best quality, I just need decent picture, decent sound, and a really good way to stream movies and TV shows from my PC to my lounge wirelessly. I don't watch sports, I just watch TV from the PC, movies, and play social games like sing star.
For the TV I think either a Samsung 55" LCD or a Sony 55" LCD, both full HD. The Sony has a better picture and is cheaper, especially things that are moving, but it has an ugly metal strip along the bottom that I really don't like. I haven't seen that particular Samsung, but I have a 40" Samsung LCD at home that works great. I preferred LCD to the plasma TV for any kind of motion, during panning or fast motion the plasma seemed to stutter at the edges, and just didn't pan smoothly.
For the sound a cheap Onkyo 5.1 receiver and speaker pack looks like good value. I know the speaker are relatively cheap, but they'll do to start with. Alternately the Edifier S550 that I have in my office sounds pretty darn good for the price, to me, if it would work with the receiver. I'm not an audiophile, I just want better than TV sound.
For getting movies/tv/music to my PC i'm told a PS3 with the free media server software running on the PC would work very well. I'll run it over the PS3 wireless, but if it doesn't work so well i'll use a Linksys WRT54GL as a repeater and plug it into the PS3. As a bonus it plays blu ray, plays games, and outputs HDMI to the receiver. My Telstra Clear digital cable box will no doubt output in some form that the receiver can handle and route to the TV.
Total price about $4500 or so, depending on this weekends sales. Any thoughts or suggestions would be more than welcome :)
