Did you see this?
The tx 8522 is just $199 refurbished, comes with a 1 year warranty. You can extend that to 3 years total for an extra $40.
They also have an 8222 for $149 refurbished, and a 5.1AV receiver for $109.
You have to sign up for their club (free) to get some of these prices.
That 8222 at that price looks like a pretty good performer if you're just listening to music...
