Center speaker to match my Infinity Kappa 5.1

[ccerezo]

I am trying to find a center speaker to match my infinity bookshelf Kappa 5.1. It was suggested to me the following center speakers that would pair well with infinity:
Definitive Pro Center 1000
PSB Imagine XC
Polk S35

I am looking for some suggestion on what I should buy. My budget is less than $500. I have a Yamaha RX-A840 receiver.

Thanks for the assistance.
Carlos.
