You sound like me about a year ago, I had an HTIB but unfortunately the one I had couldn't be connected to my Xbox for 5.1. It was good for movies and such and I started looking at other HTIB's at first but I ended up piecing the system together through the help of the AVS.com forums. I think for most people an HTIB will be great, but the more I researched it the sooner I found that for me the best solution was more in the $1400+ range. That included the receiver, speakers, sub woofer, speaker wire, and DVD player.
