Sony STR-DE 635 Parts

Hey There-


Just picked up an "Open Box" STR-DE 635 for $169 at Best Buy this weekend. I am on a somewhat limited budget and had $150 in gift cards from 2 recent cell phone purchase rebates, so it looked good to me. The only problem is that the main volume knob was missing. I figure that I can replace it for a few bucks but the question is where. Any ideas?


Other than that, I am enjoying the new receiver. I can return the unit if anyone has a better suggestion that might meet my budget and needs. What do you all think?


Thx-


Tom
