New Wheelset Time

I have been searching this site for a few days now looking for some tips on a new wheel set for my off the peg surly steamroller. I have had it a year now and new wheels seem like the best first upgrade. I have a couple hundred quid (maybe a bit more if i can wrestle my wallet off wifey) for the task. so far it looks like miche/open pro or cpx33. all that lovelyness above has thrown me.
wot say y'all

As Roberto says, you can't go wrong with OpenPros, I run them on my Steamroller. If you're feeling flush, Ambrosio Excellence are beautiful road rims and fairly rare, definitely worth a look.
