I am trying to decide on a new receiver. I am using a 8 year old Onkyo atm and it is time to upgrade (it doesnt even have HDMI). I have about $500 to spend and will be using my same Onkyo 6.1 speaker setup until I can upgrade it at a later date. I have been looking at these: Onkyo SR608, Onkyo HTRC260, and Yamaha RXV667. Which one of these is the better receiver? All of my components are HDMI: TV, DVD, PS3. The only thing that is not is my Wii. I want the best sound and options for the future as I will be keeping this one for another 10 years. Thanks in advance for any help with my options!

P.S. I will probably be getting it a Best Buy as I have $200 in gift cards atm, unless there is a far better deal online.
