I will keep the PRO, cause it plays REALLY REALLY FAST.
IF I Find the Premium plays n looks n feels really really different, I would seriously look at one as well. BUT i am not sure it would be a big enough difference to justify the $$, but will know sooner or later when i play the Premium. The lower playfield voices n red glow, the extra playfield stuff n slightly different rrules just might make it a different feel all-together ? The music makes both machines. (take the music away, and u would have to buy both Pro and Premium for the different playfield etc)
Dont forget, I have to save the pennies for the next Stern title, IF its good/Marvel Superheroes etc etc. Wondering if it will be just as good as the acca daca pinnys, or if it will be a Gomez cost cutter pin, or a Steve Ritchie game with all the extras we all want ?
