How many spokes do those have, 18 in the rear? Yikes.
There are plenty of wheels that can support your weight - what's your budget and how good is your wheel builder?
The standard response you'll get around here is to get some 32 hole hubs like Shimano 105 or something, and some 32 hole Velocity Deep V rims and get somebody who knows what they're doing to build them up. You can also order them from somewhere like prowheelbuilder.com.
