Any reason not to buy a $22k 2018 ShopSabre IS408 for a cabinet shop?

A friend of a friend is upgrading to a 5x10 machine next month and will be selling his ShopSabre IS408. It is in great condition. He is asking $22,000 if I take ownership after he gets his new machine up and running.

The machine itself seems to be what we need to make processing sheets easier for us. But are there better used options out there in the sub-$30k range?
