Personally I'd go for the Mavics. I've got a pair of Gipiemme wheels (can't remember the model offhand but they're a cheaper pair than the 024s) and the finish isn't great, the rear cones have failed after less than 2000k, and it's proving a nightmare trying to get hold of replacements – their distributor network is rubbish, certainly in Europe. I've never had any problem with Mavic equipment.
