The right receiver for my setup?

I've ordered 2x TSi300/2x TSi100/1x CS10 speakers for my budget 5.1 HTPC setup (no sub yet, it will have to come later). I would like to keep the cost of the receiver under $250, and I don't mind buying a used one if it will help the price-quality ratio.

I don't require any particular frills such as internet/3d/whatever. The only goals of this receiver is to run this 5.1 system as well as possible within the price range, and I will only ever use it with my HTPC (via HDMI).

Are there any particular stats I should look for when it comes to choosing one with the best sound quality? Or does it not really matter in this price range? I've never owned a receiver in my life, so I don't really know what I should look for (aside from the obvious 5.1 and hdmi).

Thanks for the suggestion. I could get the 1613 for $220, so I'll add it to my potential list and continue looking around.

I was hoping to squeeze some quality out for the same price by eliminating unnecessary features such as AirPlay, 3d, and less porte. I'll literally never use those extra features. But if there's really not much difference in this range I guess I'll go with whatever seems to have the most reliable feedback/reviews.
