Fair Price for Used OP-1 Field?

So I've been interested in buying an OP-1 Field for quite some time but I'm still not sure if it's the right workflow for me. I found a used one on FB Marketplace for $1475 in my area. This seems to be way cheaper than a lot of the reverb prices and the unit itself appears to be in perfect condition. Assuming everything is in working order, is this a fair price? I think there is a chance I don't get as much use out of it as I initially thought and it's quite a big purchase. In the case that I sell it, I would like to at least break-even and was wondering if you guys had any insights on what the used market looks like for these. Even if I don't sell it right away, would you expect it to retain its value for a few years as well?
