Best choice sub $500 receiver?

What would be my better choice between the Onkyo TX-SR605 ($469) and the Sony STR DG910 ($424)? I have a Sony SXRD 50KDS-A2000, Toshiba A2 HD-DVD, SA- 8300HD cable box, and a Sony upscaling DVD player. I don't need upscaling in the receiver because I think the Sony SXRD does a very good job of upscaling and de-interlacing on its own. I will likely use the receiver in 5 channel mode without a subwoofer at least initially. My side speakers are Cerwin-Vegas with 15" woofers.

Thanks for the reply. Could be that the DG810 will do as well if I can get along without the on-screen menues.

Thanks. Looks like I'll go with the DG910. However, I will still need a few more cables. I need to have the TV fuctional without turning on the receiver (WAF) so the HD8300 will keep its component connection to the TV and I'll run the HDMI to the 910 (we don't need suround sound for the evening news). I will also need an SPDIF audio cable from the TV back to the receiver for the times when I want to watch network TV OTA using the TV's very good internal tuner.

Picking up the 910 from CC today (last one in stock in my area).

Got it. Very satisfied so far.
