I find that, while a great introductory/PR opportunity for the masses, the Rare Fruit Council sales are not your best avenue for scoring rare plants and germplasm if you are already a member of the TFF. The best finds and connections to quality/rare plants is the network right here on this forum. I never go with intentions of being impressed. I like seeing people hear botanical names pronounced for the first time as if they had just encountered an alien species. I go just to do the same thing I do at home: mill around aimlessly amid a bunch of trees.
I think if you are a member of this forum, you need to temper your expectations. But also, recognize the opportunity it affords an entirely new demographic.
Just my 2 cents...
