Quoted from WeirPinball:Now the secret is out - this game is rare to find for sale in the states and goes for a chunk of change. Sold mine recently as well under the radar, but if you want one - you cannot hesitate. Just not enough to go around.
Yup, I think it really helps that all the parts are easy to get now thanks to a bunch of guys making them, both alien and full throttle are great playing games!
