Thanks. I'm passing for different reasons. CO2Arts has a great reputation and a 10 year warranty and lots of support, so buying new makes sense. Or buy one of the ones here, maybe higher quality, but and probably with the support, or build my own. But the used one doesn't seem to be a fantastic deal.I'd pass. You could probably build your own using industrial parts for the same price (or less, if you're willing to be patient).
I checked the MSRP, and it seems to be 270 USD, which is too expensive in my books.
