OK, I'll put in a plug for Pintastic New England. We have seminars, lots of vendors, and a good range of games from add-a-ball EMs to custom-themed games to most of the latest titles, and it's all in a great antique-hunting region.
If you want to play lots of titles, consider ReplayFX, too. Or maybe a trip to Vegas for PHoF instead of a show.
Finally, be sure to search here on Pinside for other discussion threads. I'd suggest searching for "which show" in the thread title.
