The Spin-X unit may give you years of service, I'm only reporting on "hearsay".
Why not nose around Canada online appliance dealers to see if they sell other spin dryer units besides the Spin X. I suggest Canada as units sold there are likely to run on 120v/60hz power. You "could" try and get a European spin dryer, but do not know even if you had 220v service, it would run on 60hz vs standard 50hz service.
Buying a commercial laundry extractor, but will require bolting down, and likely 220v service and maybe two or three phase wiring. If you are serious about this, take a peek at the eBay listing I've posted for the Unimac 202 washer/extractor. That unit features a wash tub and high G-force extractor and operates much like a twin tub. The auction also includes an older commercial extractor, but think you'll have to bolt it down.
