Jacks R Better Sierra Sniveller is a great value at $269.95 and it is what I have been using for the past year and a half.
Maybe the Golite Quilts, but the 1st version of their 20F quilt was universally considered a 30F quilt....optimistic temp ratings. The current version may have resolved that issue.
The JRBs is rated to 25F and I am a cold sleeper....I have tested it down to 22F by laying up on my clothing and using a bivy.
If you are a side sleeper, the quilt might be a bit narrow, but fact is...many of the quilts are narrow to save weight....only some of the more expensive quilts out there seem to be wider.
P.S. On 2nd review of your post, it seems that I am an idiot and did not see your $200 price limit. Sorry about that. Upon doing a quick check of the Golite quilts....they are in the same price range as the JRB. I would suggest that you consider posting on the gear swap on BPL what you are looking for and your budget. Though, if you can swing the extra money, think you will be happy with the JRB.
