There's a few threads floating around this site pertaining to the Katabatic quilts. If you keep looking (try using google, search: "site:backpackinglight.com katabatic gear"), you should be able to find some reviews/input.
FWIW, I have two of the Katabatic quilts (Palisade and Sawatch) and really like them. They're a little narrower than some of the other options and at times I wish I could open up the footbox some, but they're really well made, reasonably priced, light weight, conservatively warm (in my opinion) and customer service has been good.
The strap system works well for keeping me on top of my pad while tossing and turning my way through a night's sleep.
