i have a Sierra Designs ridgerunner 30 and i love it. it's an older model so they're going to be on clearance usually. it's a 600 fill Down, 30 degree mummy bag @ just over 2 lbs. compresses quite small (not nearly a cocunut though ^^) got mine for 109.99 with free shipping. the ridgerunner line gets good reviews and at sub 150 i think it's a steal.
