Need some help with speaker decisions...

[pokefan]

Alright, I'm new to HT's so I have no idea what I'm getting into when it comes to speakers. I just know I want something better then what comes in a HTIB. As of now this is what I was looking at.

Center - Polk CS10
Fronts - Polk R50 x2
Surround - Polk Monitor 30 x4
Sub - No Idea what I want yet.

I found a set of Paradigms at the local audio store that the guy has on sale for $300 for the pair. He said they were last years model and I believe that they're the Monitor 7's. Would you suggest those over the R50's and would they match well with the Monitor 30's if so?

I just want to know if this is a good starter set up or you guys would suggest something different staying within the prices of the above.

Thanks!
