Much underrated game,
Why ? I have no idea. I think its a great game, loads of fun and with the Gofers popping up stopping your ramp shots and taunting you (quite like the trolls in MM) Its great fun for little money.
I am sure you won't be disappointed when yours arrives.
Also if your slam ramp has damaged the playfield , Allen at Treasure Cove does a great repair decal. I bought one as my playfield had a bit of damage underneath the slam ramp, and it was a breeze to install and made the game like new to look at. Also if you have a damaged slam ramp the best quality and priced are from Mantis amusements.
Let us know the condition and maybe some pic's once it arrives.
Darren.
