There is a store in Clearwater that also builds snake racks, but I can't remember the name of it right now... Check the Tampa bay craigslist if you are looking to buy. There are a bunch of breeders in that area.
Edit Pinellas County Reptiles is a great place snake accessories (water bowls, hides, bedding, etc..) for a decent price. I've bought from them a few times at shows. The people are helpful and friendly. Their animal prices seem to be average, but they tend to shine in accessories.
