Katabatic= great quality, good fill weights. sewn in foot box which some dont like, and at least on the more expensive side of quilts. I think an all around great quilt.
Nunatek= too pricey for what you get in my opinion
enlightened equipment= best (again in my opinion) value for the feature set and the money, although I went with the nylon models vs the cuben models ( and I put my money where my mouth is by ordering 3)
another option to at least consider is ti goats JRB model of the sierra sniveler. Its lighter than the standard jrb model, is I believe exactly 20 oz and is rated to 25 degrees (I think). I also happen to have one of those and the only reason I am replacing it with tims quilt is tims is wider.
If cost is your main motivator, and getting it quick is as well, then JRB quilts are off the shelf ship tomorrow and are pretty light in the scheme of things. You can even get them overstuffed by two ounces with only maybe day or two shipping penalty.
