Well, it's good in the way that there's people out there willing to fork out a lot of money for sets they weren't able to get in person - bad in that it's unfortunate that the people that got the sets in person weren't able to keep them. Also bad in that this could be a bad omen for future JoeCons... if people going and putting out the money for these sets can't afford to keep them, then it could be a bad sign that the poor economy could negatively effect the JoeCon. Maybe next year, some of these people will just decide that last year's con was too financially draining and would be better off skipping it. (Hope not, but it's kind of a luxury in a time when not a lot of people can afford them)
I totally understand "rough patches"... I've been going through one since November and have been majorly laying off all collector spending since then. Here's hoping that selling the convention sets pays for whatever expenses you incurred from the con, at the very least.
