Does $600 sound fair? Also is this part of the machine?

Here are some more pictures

It's not in great shape, sure if it runs. I'm sure the owners would be willing to be flexible on a price

Hi, Sorry if this isn't the right place to do this. I'm in SLC, UT and the warehouse I run used to be a ski and snowboard store. They left most of their stuff here. In the back there is a Grindrite ST2600. I have no idea if it runs. Anyone who can tell me about it or would be interested in buying it...
