psw450

I was at circuit city today and saw the Psw450 for 350 bucks and was wondering if it would be worth getting it at this price or just hold out for something better. I'd like to stick to something 500 or under since i'm a 19 year old college student. Would the 450 rock my room enough (it's only 10X12 or something like that). How would it match with my 600i's, 400i, and 35i's. I'm really craving more punch than my DCM 10 inch can push out (at least i paid less than 200 bucks for it). I just want something that will shake things on my desk and feel in my gut, but I want something that's suitable for music too, since i listen to a lot of it. Basically I'd just like to know what you all think of the 450. Any help is much appreciated.
