I have 2 black OM2ns but I want OM1n's. From keh.com it seems that the black 2ns are worth just as much as the chrome 1ns so I think it would be a fair trade. My reason for trading is because I do not like batteries. I bought them off keh.com in brg condition and I think they're in pretty decent condition. I'll offer pictures ofcourse.
On the evil bay you will find that OM-1n's go for more than the 2n's. I assume it is the battery issue. I have a chrome 2n and 2 black 1n's and rarely touch the 2.
