Surrounds to match North Creek Music Rhythms?


I was wondering if anyone has any recommendations for a di-pole/tri-pole surround that would match my North Creek Music Systems Rhythm center and mains.
I built the original "value" versions with the Scan speak 9500 silk dome tweeters and Scan speak 8545 carbon fiber woofers and use them for my center and mains (3). I also built the borealis kit for surrounds but i have now decided i would like dipole surrounds in a 7.1 set up.
North Creek Music Systems does not offer a dipole surround speaker kit and using two borealis kits for each surround would be very expensive!
I am very happy with the way these sound! I finished them in dark cherry and built two 15" Lambda acoustics subwoofers to match ( 2 15" subs plus 4 PR's).
Does anyone know of a surround sound speaker that would match well for around $500 US or so??
Thanks for your help!
