I also took a look at their coordinator team, and was not too happy with what I saw. They're all cosplayers, to be expected for a cosplay convention, but they all seemed like... children. And the last convention of this type I attended that was run by children did not fare too well. The last con (not anime/cosplay) I attended ran by amateurs was also crap. I'm 100% sure I wouldn't make my $65 bucks back no matter how cheap I made my merch.
I have booth'd at successful anime conventions without making my booth fee back, and I have booth'd first-time conventions with professionals (out of town) and have made out like a bandit, so I'm gonna go with my gut on this one.
This sucks, because I wanted to booth at least two events this year. I'll have to just keep my eyes peeled for local craft festivals. I've also been wait-listed for Tora-Con, the long-running anime convention in town (the successful one I mentioned earlier). Who knows.
