Hi Jason,
IJ is a very popular machine and there are generally available.
What state are you located in?
My best advice is to not necessarily chase a game just because of the theme...unless its a game you've played lots before.
If not, then I suggest heading to one of the dealers and play as many games as you can (of different pins) and see what you keep coming back too!
Re price - depends on quite a few things...If you're happy to learn and work on it yourself - expect to pay $3000+. For one thats fully done up they seem to go for in excess of $5,000+
