I am around $9k for a new Salina and depending on what step, lift and other accessories, can be more. I think that is a bit high, but not being hosed high.. I personally would push for a new cover and try to get the price down a bit more.
Yes you can find new hot tubs in a similar price range, but not equal spas. No way you will get a Hot Spring Highlife series that is comparable anywhere under $10k. If you are in the $6k - $7k range new, Caldera Vacanza and Hot Spring Hot Spot series, Jacuzzi 200 and Sundance 600 series, Bullfrog x series, maybe a stripped down Marquis e series and I'm sure Artesian and D1 also have spas in that price range.
