The brand name is not sought after by collectors so you're not going to see ridiculous pricing like you would with a Wilton. For 75 bucks, which is a good price, you got yourself a hulk of a vise that would be overkill for the majority of us. Around here, you paid what the vise is worth. In other areas, you could double your money. The problem you have, like mentioned already, is you're confined by the economics of shipping. You would have to find the over the rainbow guy locally. Shipping it in two pieces is a risk that I wouldn't want to deal with given the slim margin and all the leg work you have to go through. If this was mine, I would clean it up, paint it and then see what happens with a local sale. It doesn't eat so keeping it around for a while won't be a problem.
I have a hard time leaving a nice vise behind so I understand why you dragged this beast home. It will be a fun project to restore.
