Accessories4less.com is a good source for discounted AVRs. I'd recommend Yamaha because they sound good but also seem to be a step up in reliability relative to most others. If you don't need all the absolute latest bells n whistles, you can save some $$$ buying the previous generation models like this...

Yamahas dont have have the most robust power supplies out there though, and I'm sure your Aerial center needs some juice. But since you won't be using all the AVR's amp channels I thought it could still be fine and you may even be able to biamp your center.
But here's a Marantz that's got a beefier power supply and is even cheaper...

My problem with Marantz (and Denon) is that last year they were bought by a private equity firm, and their motivation is usually to cut costs so I'd be concerned about parts quality and reliability.
These two i recommended are probably at the absolute minimum for each brand to meet your needs, but they're still well below your max budget so you might want to move up the lines as you'll get more power and still be within your budget.
All this said, what I'd do would be to buy a used Anthem MRX710. To me, it's a cut above these others in parts, build, and sound quality, they're reliable, and they have what many feel is a superior and proprietary room/speaker EQ system. Here's a nice demo unit that's in your price range and probably still comes with full factory warranty. This is absolutely what I'd do if it has all the features you need...
