[Need help on a new low priced receiver]

Terrific links! Thank you very much. We are going to purchase the Onkyo, it has great features.  You saved us a lot of time. Really appreciate your help.

[Need help on a new low priced receiver]

I have Klipsch Synergy SF3 floor speakers and Synergy center and rear speakers along with a sub woofer.  Our left and right floor speakers are 8 Ohms and 100 watts.  The rear speakers are 8 Ohms and 50 watt.  We need a new 5.1 surround sound receiver and need help in knowing what would be a good match for these speakers.  Is there any in the range of $300?  Appreciate any help you can give me.  Thanks.
