Buy this receiver:
http://us.marantz.co...oducts/2205.asp$1500 MSRP you can find it for under $1K if you shop around
1080p up-converting
full HDMI 1.3a compliance including all of the new HD audio formats, deep color, and SACD
XM radio
Dual Zone functionality
110W RMS x7 channels
and of course fully THX certified
if you want something a little cheaper you can go with last years model:
http://www.accessori...item/MARSR7001#which is pretty much the same except it only supports up to the HDMI 1.2 spec and only up converts from 480i/p to HDMI
or you could got with the SR6001 (MSRP $1200) which is the next model down and offers similar features to the SR7002 but 2 less HDMI inputs only 100W RMS per Channel and it's not THX certified but it does support HDMI 1.3a which IMO is probably THE most important feature if you're looking to futureproof.
Onkyo makes nice stuff but like Sony and HK they're not consistent since they make low quality stuff as well as high quality stuff.
so when you buy something expensive from them you don't necessarily know if they started with a $5K receiver and stripped it down or started with a $200 receiver and stuffed it full of extra features.
Marantz and Denon ONLY make high end stuff so when you buy that<$1000 receiver you know that they started with their top of the line model and removed some of the expensive features for the budget minded.
I've used Marantz equipment for year, the only time I've ever replaced them is when I wanted something with more features... their quality is phenomenal.
If you're still interested in that Onkyo unit you can get a refurbished unit here pretty cheap:
