I bought a Dreammaker Big EZ this spring and love it (I posted a review at SpaDepot if you want to learn more). It does use forced friction to heat (contrary to what others said above), which makes it easy on the wallet. Yes, it takes longer to heat the water on fill-up, but that's not a big inconvenience to me. If it's a concern of yours, buy one of the new hybrid heat models, which have a supplemental heater--the cost is only a few hundred $ more. As an aside, Dreammaker support is awesome. They helped me with an ozonator installation problem I had (returned my call within 10 minutes). If you want a spa with lots of bells and whistles, this is not the one for you. However, if you want a reliable basic tub with adequate jets and a great price, I strongly recommend Dreammaker.
