Dr. Dude is a great looking Pin IMHO. Probably the best looking of the 3 I own. It was my first pin years back and I bought it cheap and in relatively rough condition and fixed most of it. Still the game play is not all that exciting. My biggest issue with it is you basically are playing with half a playfield and not really much in the way of multiball.

Whirlwind would be a better choice. Does it have to be a system 11? Otherwise maybe look for a WCS94. I don't care what anyone says about the theme, that game is a buttload of fun to play. I didn't even want to play it and my 8 year old made me and we had a blast.
