When these were new they were very expensive.
I have fixed several of these. There is a pneumatic system and an air cooler that can get condensation in them and cause problems. Not sure if they ended up putting an air dryer on these to reduce this issue.

Not many examples of these newer bowlers to compare with. Assuming the machibe is working. And being sold as is where is I would think a friendly sale would be around $1000 and a top price might be $2000. If you buy from a retail shop and they deliver and cover a warranty it might approach $3k.

These are a real pain to move. This will take you the better part of a day and you will need help.
