I would only recommend a Yamaha 1800/1900(preferably the 1900), or Denon 2808/2809.(or a higher model from either)
Remember that the 8 in 1800 is the year, and the 8 in 2808 is the year. Dealers should be giving a good bit off of these units, and you should expect to pay more for the 1900, and the 2809.
Some like Denon, some like Yamaha. When it comes down to it, for me it just depends on the deal of the day. I would purchase either. I have ended-up with Yamaha for my last two, and I loved both of them.
Of the four receivers I listed, the Yamaha 1800 would be my last pick. If it is not a good bit less than the 1900/2808/2809, I would look to those three.
Onkyo will give you more for the money, but I believe the quality is better with Denon and Yamaha. It's just a personal opinion, and many love their Onkyo receivers.
