Thanks for all of the advice everyone. I decided to go with the Avengers IQ Pro. I played the Alice Cooper again last night, and while I really love the theme and the look of the cabinet and playfield, it was just too hard. The Avengers is just fun to jump in and play, and I've barely even started to figure out the rules, so I know there will be enough depth to keep me interested as I learn the game. I'm really surprised I ended up with this one, as I wasn't really excited by the theme and almost didn't even try it, but once I played it, it was the one I kept coming back to and had the most fun with.

I'm really happy that I live close to the Pinballs.com showroom and was able to play these all enough to determine what I wanted to buy. Mike is great, he want's you to play as long as you need to in order to make a decision. He told me to come back as often as I wanted in order to make up my mind. He was also kind enough to offer that if I wanted to go with the JP Pro, that he could lend me the floor model so that I could have it for Christmas and then swap it out for the NIB once it was delivered. I'd say that's excellent customer service. So if you're anywhere nearby, I'd definitely recommend them.
