I ended up with a spare set of these and I was wondering what a fair price for them is, I checked ebay but couldn't find any for sale or that have ended in the past little while. The last time I sold a set I was offered $50 for em and I wasen't sure if they have come down or not.
I paid $12 on YJ for a complete full set including the Microns, the figures and the three (I think it was three) larger gold figs. After fees and shipping, it came to around $25, I believe.
