Newbie here! Looking to add a second machine to what will eventually be a music collection. Looking at AC/DC. Problem is, I don't know which I should be looking for. I don't like the Pro version with Angus' big ugly face so that's probably a no. It may come down to an older premium model with the clear glass for the lower PF. I see the early production had some problems with that. The newer version has removable glass which is great but I'm seeing videos that show out of the box the glass is uneven and has to be adjusted before play. I don't really want to deal with that. Don't really care for the lower PF but like the bell, the moving band members and the look of the premium. The new pro without the big ugly face doesn't look bad but may play a bit boring? I also see some bad reviews on Sterns new model in regards to the lighting and a few other things. Opinions from you educated folk?
