mikes.105, Heres some CR18 rims to look at: http://www.ebay.com/sch/i.html?_nkw=Rims+Sun+CR18 . A search also shows they're available in 27" if you don't want to change brakes, but the best part of a 700C conversion is the dual pivot Tektro long reach brakes you can install. I put a set CR18 rims my tourer last year and have been quite pleased with them.
