I'm just getting back into diving after a 10 year hiatus and I can't imagine going back wet, so one of my first purchases was a new CF200x. Not that I looked very hard, but I haven't even seen another brand of dry suit being sold in San Diego. As for them pricing themselves out of the market, back in the early-mid 90's the CF200x was about $1800.00. 10 years later I paid $1900.00 for the suit with zip seals and rock boots. Not much of a change. If anything, I'm getting more now than I would have 10 years ago. Are the suits cheap? Definately not, but I always wanted one when I was a little diver and since I no longer get deals like I got on my Viking sport ($400.00 new) I figured I might as well splurge.
As for leakage, we'll see. My first dives in my viking were wet ones since there was a recall on the zipper at the time and my suit somehow missed quality control. It wasn't their fault though. The suit pressure tested fine. It was only when the body was in certain positions that the zipper leaked. After the zipper was changed, it was pleasure to dive. I guess what I'm saying is that everyone has their leakage/flood stories and more will post about bad experiences than good ones.
DUI is a fine suit, so is Viking for that matter. DUI is a little more expensive than the rest, but at this point, I don't see them making major price increases that would likely drive them out of the market.
