I'm thinking of going to TPF. It will be the first time going to any pinball festival/expo so I don't know what to expect. But one of the reasons I would go is to scout out buying a machine for the home. I know they have auctions there, but what else can I expect there? Specifically in terms of value? Are festivals pretty good price-wise? And if I bought one, am I on my own as far as getting it loaded up (important for me since I need to know if I should bring help for the trip . I'll be driving from about 4 hours away so too far not to be prepared.
