Welcome to our forum.
since you are a jacuzzi dealer it does make sense that you recommend that
My 2 cents worth, buy from a dealer that you can walk in the store and ask advice from, or can call or again come in and talk to if the spa needs service.
Sorry Brill and VSC but I would avoid online or box stores if there is a way. To many bad experiences have chased folks away from the hot tub world because it didn't feel like they expected or was more work because they were installing parts that were shipped to them, or they couldn't get an answer about water maintenance fast enough from a forum it was noisier than they expected or the online retailer became unavailable because they changed their name or went out of business. Check your local dealers first and see who is around, how they treat you and if you can, please wet test a few to get an idea of what's comfortable for your butt instead of relying on some online sales guy or a picture to tell you how comfortable it is.
I wet tested both today and ended up purchasing the Hot Springs Relay....I ended up getting it for $5700 and it's being delivered Tuesday on my wife's birthday. Thanks for all of your assistance!
