Thanks for the info guys... it gave me some better insight into it all. Bottom line is I cant afford to spend much, so I'm going to with a lower priced setup, and then down the road (likely when the plasmas are working and priced well) I'll get a better setup.
Now the other issue I'm having is setup... My down stairs isnt the best setup for a sound system, because its long, and narrow. So... i can not pull the coach out, and have the speaks behind me, so I'm planning on mounting them on the wall, and angling them down.
Here's a few screen shots of my basement (dont mind the mess...we are slowly working on removing wallpaper, carpet, and painting.) On the screen shots I indicated where I'm planning/thinking about putting the 5 speaks, the subwoofer location is still undecided. The big tv is obviously going where the small tv and wall unit is now.
I guess my main issue is going to be where to place the rear speakers...
