Front speakers for a Polk Audio CS245?

I'm planning on upgrading my speakers and am considering keeping the center Polk Audio CS245i. On a budget of ~$500, any recommendations on a pair of front speakers that would match the CS245i well?

Any of the RTi Polks should be a perfect match. If you don't want RTi's in the front, I'd also upgrade the center to match whatever fronts you are getting.
