That's basically what you'd be paying if you found him in store today, so that's about as good of a deal as you'll come across for a while.
I've bought a couple of figures loose due to how scalped a lot of them are. As long as they're in good condition and have all their accessories (or at least the important ones like with my second RotJ Fett) they're usually worth it.
Since they're used though when I get them I usually give them a nice "bath" and cleaning... I'm not a germaphobe but the I don't like the thought of a previous owner touching them with dirty hands or something.
