I own a '99 Saratoga Pavillion. It has been a good tub for us (a couple of small problems, but nothing that couldn't happen to any manufacturer, and they were resolved satisfactorily), and when we purchased it we felt we were getting one of the best values on the market. It is a well constructed spa (strong frame, good shell, good cabinet) and they use the same components that are found on most of the top manufuacturers. At that time, our opinion was that their quality, features, and hydrotherapy was as good as any, and it was priced much below comparable products from most of the well-known brands.
IMO Saratoga is a good option to consider, but only one of many. I haven't shopped spas much lately, other than noticing prices a the dealer and at home shows or fairs, so I can't comment on the deal you are considering, but it seems to me that in general, Saratoga's prices are now closer to the rest of the market. Other manufacturers have introduced some tubs/features that I find very appealing, and I think there are a lot of good choices in your price range. Consider them all, and wet-test the ones that you really like. That will mean more than comparing the specs. Don't worry about missing a "deal" on this tub. If you are patient, almost every dealer can help you find a good value. Don't forget to evaluate the dealer as well as the spa.
Good luck!
