Beachcomber is well known and appreciated here (partly due to Steve, a Beachcomber dealer, doing lots of support to people here), and I almost bought one. Nice dealer close to home, nice spas, very comfortable. We ended us choosing something else for our own reasons.
But if you don't have a reputable Beachcomber dealer near you, I'd said forget it altogether and don't worry about it! There are so many great spas around that you shouldn't stick too much on a product you can't even sit in! Evaluate what brands you can find around you, and if you like the Caldera after a wet test, go for it!
