Center channel to match ELAC Debut 2.0 6.2s?

I recently picked up a pair of the ELAC Debut 2.0s to kick off setting up my 5.1 home theater (after wanting to start one for years). I'd heard great things about the Debut 2.0's and so far, have been loving them. I am now looking into picking up a center channel to boost up the dialog a bit.

I would like to find something that roughly matches audio well with the Debut 2.0's and isn't wider than 19 - 20 inches (thanks to entertainment channel restrictions). Budget falls in the $250 and below range. I haven't heard very good things about the ELAC C5.2 center channel so I'm not too interested in that (it also is too large for the 19-20" limitation). I have looked into some different options including the Klipsch R-25C (though heard that was a really bad pairing with the ELAC's), the Polk CS10, the Pioneer C22, and the Pioneer Elite SP-EC73 (though it falls outside my price range a bit).

Any suggestions or input on speakers I've already mentioned would be greatly appreciated! And thanks in advance!
