With an $800 budget I'd recommend going 1 of 2 ways. If you don't mind running your DN receiver to the tv via HDMI for video I'd recommend going with a seperate component system. For example:
2 pair of Athena B1.2 Bookshelf Speakers $240
Athena C1.2 Center Channel Speaker $149
Bic H-100 Subwoofer around $200
Onkyo 504 receiver $179
This or a simular setup would give you much better preformance and better quality components than included in a HTIB package. The speakers and sub are usually cheaply made so they can compete with the package at a certain price point.
HDMI receivers are somewhat higher in price so If you want to go with an HDMI receiver so you can use the receiver as a hdmi video switcher as well, then I'd recommend this which is well within your budget.http://www.shoponkyo.com/detail.cfm?...il=1&ext_war=1
You still get a high quality receiver as Onkyo and Yamah includes in all thier packages but as stated above the spekaers and sub will be of lower quality.
