Not a bad looking piece of iron.
Personally, when I had my smaller shops, a jointer wasn't high on my priority list as I didn't have a lot of projects that required it and didn't want to use up the space in my shop. So I'd look at your what tools you are needing and purchase accordingly. If you're looking at it for resell after you restore it, I doubt you'll bring much more in than what you're paying. Offer $15 or $20 if it's a restore and you may make another $10 - $20 depending on what you have to do to it.
Just my .02
