I've seen them around. Not as nicely done as Deep V's, certainly not as nice as CXP-33's or Open Pro's. The join was a bit rough, the milling on the braking surfaces had a couple glitches, and the powdercoat had a few weak spots. Also, I happened to build them up for a friend who bought them and we were going to use standard Sapim nipples. About half a dozen of the nipples didn't seat properly until we'd countersunk the spokeholes from the inside to get rid of excess metal. It was also apparent that the extrusion thickness varied noticeably, usually a sign of poor extrusion control or a worn-out die.
Plus, you won't have much resale value in them. I'd suggest you stick, for less money, with the standard rim choices.
