In 2004 I paid about $6700 for a Cayman which is basically the same tub. Prices have increased somewhat drastically since then.
My tub included a circ pump, 56 jets, 3 therapy pumps, ozone (not he upgraded system), SS jets, single LED light, plastic skirting and coverlifter.
Basing what I paid and the fact an increase in about $1100 over the 2 years, my opinion is your not too far off in price. But I will say that pricing is different all over the country ... my price is a NJ price.
