Low Cost Surround Speakers Decent Monitors

I am putting together a decent audio system for my daughter (25). She lives in a small apt. is working hard and has no dough. I have very high end and haven't really investigated reasonably priced equipment. I am upgrading a bedroom system with the Lexicon RV5 and giving her a nice Rotel integrated surround system. I got her a Panasonic 42" plasma and am looking for decent speakers for the surround. I am giving her a nice M & K sub that will work in the space. Help. What are you thoughts on the speakers?
