I have a strange RB and have had constant offers for 2 ref, I don't think 1.66 is a fair price but I could easily be classed as bias considering I have one, but I could quite easily sell mine for 2 ref right now, If I wanted. I'll wait for more comments or trade links before voting though, just throwing my comment in.

havent tried to sell any of mine, nor have i seen any being advertised on the trade servers. I have to default against a change without any justification, but will give it a day before doing so

Over 400 posted or bumped in the last 2 hours on Outpost. Found several dozen for 2 refined that have not sold. Price gouging is apparent.
