Sure the dealer is going to say so, he's making a big margin on them. I'll repost what I wrote on another bulliten board a couple of days ago.....
All spas are going to incorperate air into their jets to give them a more vigorous feel. The components that just blow air at you are not jets they are air injectors. This is one problem I have with Royal, they artificialy inflate their jet numbers by counting the air injectors and listing them with the total number of jets. They also claim that electronics are a bad idea for spas. Well, I imagine that they are also a bad idea for washers, driers, refridgerators, stoves, ranges, autos and houses, but the fact is, they make things run more efficiently. With things like self diagnostic programing you will have fewer service calls in event of a failure. Tell 'ol Bob to come on in to the 21st century. Beyond that they contradict themselvs on that electronics aspect by puting a digital read out on their top side controler. OK, next, they claim a 6 year warranty. I'd suggest you get a hold of a copy of that warranty and READ. It comes out to about 1 year at best. They use zero insulation on their plumbing. It's a good thing they dont use any glue and only hose clamps (another lie by the way) because that thing is going to need to be easily accessable. They are a cheaply made tub being sold at premium prices, because they are usually surrounded by high end spa retailers. If you want any more specifics, just let me know.
