Sorry, this trusty little machine that washes the heck out of cars has been discontinued by the new owners of Superior.
They now emphasize a surface-chain tunnel system for a reason that is lost on me.
My distributor bought a new one himself after I did. The cost was well below average for an IBA. Base was about $65k I think and went up from there with add ons like spot free rinse.
Perhaps you could get a used one, however factory support may be an issue.
I get around this due to the simplicity of the machine, wide availability of many non-proprietary parts, and an excellent distributor who also stripped many parts off his old machine before scrapping her.
