I will be buying a new machine in a couple weeks, or at least I will have the funds to, and I am torn between two of my favorite pins. Scared Stiff has lots of flow and just general fun with a great theme and lots of humor. Champion Pub has a TON of character and has always been one of my favorites, even though it is so different from normal pins.
All things equal, which would you buy? I tend to only keep machines 6 months or so, although both of these could stick around longer, so resale value and demand is a factor in my choice.
