I think several manufacturers/dealers will have a spa in the $5,000 range. Granted, it won't be their top of the line model and won't be right out in the middle of their showroom, but you should take comfort in knowing that you're dealing with a local person. There's something to be said for being able to walk in to a store and look somebody in the eye and wet test the spa you're interested in.
Local dealer explained it to me. Good, Better, & Best. They carried 3 types of tubs. The more you pay, the more you can expect.
By the way, you should be able to find an Artesian Island Spa in your price range.
