are the 31 in 1's uncommon? i thought they were quite easy to find, i've got a orange famicom 31 in 1 that had a us gold converter attached to it for $1, i figured that's all it was worth
Either way, that's a heck of a deal for a system period! That 31-in-1 is semi-common (I have two copies of it), but it alone would fetch $25 I'd imagine, if the auction didn't get pulled by ebay.
Yup, NES multicarts are generally more in demand than the Famicom counterparts. I think they're just more collectible in the US, and there's not quite as many out there as there are Famicom bootlegs.
