Just ordered a Beachcomber 730.
Thanks to all the people on the Forum. Good advice, opinons -- with some facts thrown in.
We selected the Beachcomber 730 -- based on the Wet Test and a very service minded dealer here in the Mpls/St. Paul area.
Aside from the service, and the wet-test, most people have overlooked Beachcomber "made-to-order" capability. For our installation (where the Tub is butted up to our deck), it was helpful to order the Pump on the opposite side of the front panel. This will allow me to service the unit -- without having to "drain" the tub -- pull it away from the deck and then move it back. Worst case would be to crawl under the deck and attempt to service the unit while crouching below the deck joists.
