Ken,
We just purchased a Certa in October 2009 (we love it). We paid $6600 and that included setup and delivery, steps, cover lifter, start up chemicals and ozonator. I feel we got a really great deal and our dealer is fantastic and we've heard great things about them just through word of mouth. We're in the northeast just so you know what area of the country for comparisons you may receive. Make sure your dealer will be there to support you after the sale for service, questions, etc. The product is only as good as the service and support you receive.
You'll be in a spa in no time!
