JD fits your criteria, lots of multiballs esp in the supergame and also has a mid flipper, I think the machine is dull personally, maybe see if you can spend 30 mins with one to get a feel for it before you take the plunge, saying that you can always shift it for the same money if it's not for you, maybe post on here for things to look out for if you decide to go for it, make sure the dead world works, indents @ the ball drop rollovers, wear behind centre targets, right plastic ramp often broken at ball exit mount, chimney plastics often broken at mount also, cabinet fade and lockdown bar holes otherwise they are generally OK.
Owned two, both felt clunky.
Flintstones is a better game for similar money IMO
