KLH HTA 6108 -- now what?

Trying to build an HT on a really low budget I just picked up a KLH HTA 6108 for $50 off best buy, while I'm still not sure if it was a good idea, I'm wondering if there are any recommendations for the a/v receiver I should get?

I found a Sony STR-DE595 for about $170 but am not sure if that's the right option for me considering my inclination to save as much money as I possibly can while still have a somewhat respectable (?) system. (if I still can?)

Suggestions for an a/v receiver other than the one above? or should I just ebay my KLH subwoofer/satellites and stop saving money? :confused:
