Help on deciding new HTOB?

Kennith offers some very good advice. All I would add is that if you don't like the HT-S5100, why not try the HT-S6100 (or above). It switches HDMI. But, as stated above, buying a receiver and a speaker set is a good compromise between an HTIB and buying a receiver and 6 individual speakers. I have Polk Audio RM6750 5.1 speaker set. It's a humble source of sound, but it works really well for movies. And at ~$230 you can't really go wrong. I paired those with an Onkyo TX-SR606, bought a few HDMI cables at monoprice.com and got some lamp cord for my speakers at Lowe's. It really can be done easily and relatively inexpensively.
