WTB: 0F (or close) Western Mountaineering or Feathered Friends bag

Hi all, 

I've been pushing the limits of my 20F FF bag since moving to Colorado and getting tired of being cold in the winter. I can't afford a full price new bag so hoping to take a good condition bag off someone's hands! I'm 6'0 and open to either 6'0 or 6'6 bags. Ideally I'm looking for a 0F bag since I'm a pretty warm sleeper but open to -10F or 5F too. Only interested in Western Mountaineering or Feathered Friends, because, well, they're amazing and worth every penny...if only I had more pennies.

Thanks,

matt
