I don't know about a good deal (I guess it is if the machine is minty fresh, which it seems to be), but it seems like standard price for a Pachinko/slo.. most of the others have Buy It Now prices of more like $175, though, which is what leads me to assume it's rarer (or at least that I won't see 10 more of these this month).
I just picked up an APB dedicated, though, for most of my spare cash.. no choice but to pass on this one
