I bought an AC/DC premium because the PRO seemed so watered down. I do love the ACDC premium, but since I had my fill of it and moved on from it, I would go PRO in a heartbeat to save some cash from the premium, because I had ''been there done that'' It is a great polished pin in either pro, or premium.

As for Metallica Pro, I absolutely love it.
I played the premium first, (and have since) and do not like the hammer that blocks the playfield at all, I don't need a snake jaw that moves, I don't care for the mini subway (slows down gameplay) Don't care for the rising cross. I do like the premium spinners, but I'll live without. I went PRO all the way and have had no regrets. While the code is still a baby, I love playing this pin. Love the shots and gameplay, I find it very addicting.

I bought mine with about 60 plays on it, full led kit, cliffy protectors, perfect in everyway. I'm in to it for about $4300 and have had no regrets.
GL!
