I'm looking into getting a new sleeping bag and I am on somewhat of a budget, like under $200. My trusty old slumberjack 30degree I've had since I was 9 needs to retire to the back-up position. I am looking for something lightweight, packs pretty small and in the 20 degree range.

I saw a few decent reviews for the Kelty Cosmic Down +20, and it seems like a great bag for the price. Any other suggestions would be much appreciated!
