A/V reciever advice

Hello,
I just finished building an office in the basement and looking for an AV receiver. What this will be connected to is my PC, and Satellite receiver, TV and a 5.1 system of speakers. The Speakers are nothing special, 4 in Ceiling speakers and 2 In wall Speakers a sub and a Center channel. The ceiling speakers have two different configurations, depending on if i am watching TV or using the PC (Mainly Gaming and iTunes). I do not want to spend a a lot on the receiver at most 500 since this is not my main system.

The probelem is there are so many brands out there and some of the brands I am familiare with the quality was gone down.
For my main system I have Denon A/V reciever, Anthem Amp, and Paradigm Speakers. But I have heard the Denon's quality has gone down. If not Then I will stick with Denon.

The brands I am familiar with are Yamaha, Onkyo, Denon, NAD, Sony.

So looking for advice on these brands and other that might fit the criteria.

Thanks.
