Maybe the sales guy meant, OEM....like Balboa. Loads of tubs have Balboa controls. Or Waterway, loads use Waterway pumps and jets. And how many actual presses are out there for forming acrylic, more than 4 I am sure but do they all get there sheets from the same company or two, I bet so? Only a few motor brands hooked to those waterway pumps. And a few heater boys. Just some thought.
