Members of Des Moines Pinball League have lots of games that you can test out. Not all necessarily for sale...but it will give you an idea of what you machine you might want to look for.
Stop by Jordan Creek Mall theater arcade on Monday nights @ 7pm and get to meet the members. A great bunch of friendly people. We will be meeting the next 2 Mondays (12/7 & 12/14) but then will be on break for the holidays for a bit.
