Anyone have exp. with these wheels? The good and bad on them? Customer service?

I need a new wheelset, trying to stay in the 1500g range and not above $1,000. Looking for best bang for the buck.

So far I'm interested in:
Campy Shamal
Williams Sys.30
Mavic Kyserium SL
Fulcrum Racing 3

I can purchase any of those below or less than 1k. Any other suggestions? I'm 145-150lb, ride mostly rolling hills to mountain passes. Rarely flat land and around 4-5K miles a year.

My Reynolds Attacks have a warranty issue and I'm returning them. I bought them a 9 months ago at an on-line overstock place for a great price but they currently don't have any more in stock so they are giving me a refund.
