I know I am going to get a lot of down votes for this but Hobbit would be my choice, it is the one all my kids play. Also in the secondary market it offers one of the best values for the money. I have all three of JJP machines and my kids play Hobbit, DIaled In, and then WOZ. WOZ is a very difficult pin for kids, they struggle with the shots and rules. Hobbit is much more forgiving, easier to get multiball, easier to progress through the game. DIaled In is new they like what it has to offer but will revert back to the hobbit. There are many criticisms of Hobbit and they are valid, but if you have kids and want to get the best bang for your buck Hobbit is a great choice. My last comment is that if you are an average player you will enjoy Hobbit, I have had it for a couple of years and have only beaten Smaug once. My last piece of advice is to have your kids play the machines.
