1: Sorry, bit of a pet peeve... It's "recommend TO me" or "recommend FOR me" or something along those lines... "recommend me" sounds like something you'd hear out of those poorly dubbed Godzilla movies, or that "All your base are belong to us" that is now iconic of some of the really poor translation efforts of yesteryear.
2: If I'm not mistaken, the PS3 has optical/TOS-LINK output abilities, so any surround receiver or home theater in a box system that has at least one optical input, will work. And while on the general subject.... Optical cable is optical cable. There's no such thing as a PS3 optical cable or an Xbox 360 optical cable. It's just an attempt by some shameless companies to sell maybe a $5 cable for $15-20. ANY TOS-LINK cable will work. So, if you're at a Best Buy or something like that, be sure to check in the home theater section as well as over by the game consoles. Sometimes they'll have better deals in one place or the other. One other tip... Unlike other cables, where there is some marginal benefit to be had by buying the "gold plated" versions... Optical audio/TOS-LINK cables are all really pretty much the same. There's really no benefit to buying a $20 Monster brand TOS-LINK cable vs. some $10 no-name cable. Probably came out of the same factory off the same production line, one just got put into the Monster bag while the other went into a no-name bag.
Alright I am looking to get surround sound for my PS3, can anyone reccommend me a system for under $400 that will be compatible?
