These machines are increasingly difficult to find in good condition and reasonable price. If space is the only issue, you might consider a foldable camping table. Also it does not need to be connected to water to work.
In summer, I set up camping table outside and put the CPP2 on top. Use one 5-gallon bucket to fill up the machine, and another to gather waste liquid. And an outdoor extension cord for electricity. In winter it will be slightly more difficult, but still doable inside the garage as long as I can withstand the temperature myself.
Just my two cents. Really great machine to have for my 8x10 processing!
