I go to this show all the time - the only reason I'm not going is because I went to an InterGem show in Hartford (which was really small) the first weekend of October and the Whole Bead Show in NYC last weekend.
It's very different from BeadFest - this is truly a jewelry show - about 80% of the vendors sell finished jewelry - gold, precious stones, silver, etc. There are always a lot of bead and pearl vendors, and you can get better prices because it's not a bead show. This sounds odd - but it's been my experience that prices are generally better at an Intergem show than at BeadFest - I think because it is probably cheaper for the dealers (table and set up/contract costs).
I'll probably regret not going, but I can't go to EVERY beadshow, can I?
