Don't know about the Hot Spring, but the prices for the two Calderas look good, at least compared to the prices marked on the 2009 Utopia Series spas at a store near Seattle. Seems like they were over $10,000. I didn't try to negotiate their prices. I bought a 2008 Caldera Martinique, which is one step down in class, for $6500, with the same extras you list plus the GFCI box. He was firm at that price, wouldn't drop it.
