This is one of my all time favorite games but it isn't the deepest or most insane pinball machine ever made or anything. I just happen to enjoy it very much dating back to the early 90s when I played it a ton.
They are very difficult to come across in some areas, and $1400 is a very fair price for one in my opinion. My friend sold his last one (and the only one I've seen in this area for sale) for $2200 and it needed shopped pretty badly. I have one on the way to me via freight right now as we speak. I traded a sega Frankenstein for it and paid to have it shipped out here from New Jersey.
