I've been to a bunch, but I haven't paid for an autograph for a long time. I pretty much feel duped if I pay money for someone's scribbly written name when I already own several DVD's of their work. It just feels slightly insulting as a fan. But I love the dealer rooms and the Q&A's. The people there are really cool and friendly even though they're 90% of them are "weird" by conventional standards. They're a fun time overall, even if I don't get autographs.
