That's pretty cheap, depending on it's condition. I just got a used one for more than that price, in pretty nice shape.
I personally don't care about "pretty" as much as function, so I would just check it out for that. Move the moveable jaw almost to the fixed one, and tighten the moveable jaw adjustment until it drags when you turn the handle. Now move the jaw way from the fixed jaw. This should show you if the ways are worn out.
There are a dew links online on rebuilding or tuning them up. Sweet vises!
