I was able to get the Maths Nightmare avatar for the second time (legitly) and not only on the reset day. I know there aren't so much people that are able to do it, and I think some people would like to buy it. I'd be selling for legit neopoints, when I'll turn level I. So, price check, now. How much would you pay to get it, in nps ?
This belongs in the Black Market section of these forums, which you can't access until level 1. To give you a general idea, though...there's another user on here who can legitly get the Korbat's Lab and Escape From Meridell Castle avatars who charges 250k for each. I'd say in that range.
