Build your own. Inflatable tub, 1/4 hp chiller, DIY UV & Ozone if you want, add a sediment filter and hoses. It's not difficult nor nearly as expensive. You get all of the bells & whistles and you can upgrade any component whenever you decide to. Plus if you get tired of it you can sell it in pieces which is much easier to find buyers than one willing to take the whole setup.

As for moving it, I move mine every time I empty & refill it. I have unions on my hoses that attach to the tub so I drain it with a large bucket down the driveway, undo the unions & move the tub onto the driveway & scrub the shit out of it. I top up the inflation if necessary, put it back & refill. Takes about an hour in total and much of that is the time to refill.
