I have a dude... As stated not very deep but can be fun and definitely a machine you need to get physical with to keep the ball in play. It's a bit of a sleeper pin because you can get it cheap and it grows on you... Like a fungus. I find myself singing the songs in my head during the day sometimes. Plus it's a nostalgia piece for me. Party zone has a DMD though and a little more going on I think. Tough choice but in the end it's Dr. Dude for me.
