It looks like a Tornado "Sport", which is one of their lower-end models. Google that and check craigslist and you'll get an idea of what others are asking for a used one. You can pick up a top-of-the-line used Tornado coin-op in excellent condition for less than $500 (I got mine for $350) so I wouldn't pay very much at all for a Sport. In fact, I'd just get a used coin-op and pass on this one.
