In reply to lumu_tit:
Friend of mine bought an "alledged" Planet X cyclocross frame direct from the manufacturers.
I can't remember specifics, but he's had problems with it - something to do with the bottom bracket delaminating, which he's had to epoxy back himself.
Now, he "may" just have been unlucky, but, as someone else said, I'd rather trust my Campag carbon wheels than something I've never heard of, even though I've yet to hear of a death purely due to a failed carbon wheel.
Having said that, I've broken an alloy wheel on a pothole, so any wheel could go at any time.
If I were you, I'd be looking at sales - for example:
