Hi,
I too am deciding between 2 or 3 beachcomber models. Unfortunately I can't wet test them all!
I also tested Jacuzzi and HS. I liked the moto massage, but I also prefer having jets on both sides of my spine. I've also enjoyed time in a HS spa on vacation and found that I didn't leave the moto massage on for very long. It is a nice feature...but the vanguard has 2, which IMO reduces other jetting options. Have you looked at the Envoy?
The beachcombers I'm deciding between are the 720x, 740 and 750. I wet tested the 740 and loved it, particularly the deeper footwells with footblaster jets.
Haven't tried a 750 but the seating options look amazing.
I am hoping to try a 720x tomorrow. Unfortunately none of these are the LE models.
I'm still trying to decide what to do about that.
Just as everyone on this site recommended, the only way to know what fits you best... is to wet test. They also said I can't go wrong with any of these models, and I think that's true!
Good luck in your search and let me know what you think after your wet test! IonHeaven
