I have one that I just finished fixing up.
It's a Good game, but not a Great game.
The playfield has a good variety of shots, there are a ballanced set of shots from the left and right flipper, the multiball is fun, and it has a DMD.
Unfortunately the DMD is the "small" one and it has less than stellar animations and graphics, you have to remember that this was one of the first DMD games. The ruleset isn't very deep and the play does get repetitive, and if you do not like turtles, this game will annoy you quickly.
That said, it is probably one of the cheapest DMD games out there.
Make sure that the shooter works correctly, Data East used a shorter shooter rod on this and it is very hard to find a replacement.
