Agree with the others here. The Ed Krynski/Gordon Morison machines are both cool looking and fun.

Fewer players = less stuff to go wrong and lighter.
Solar City, Target Alpha are great drop target games but why stop there? Get a Canada Dry!

Just know Rare Hero will loose respect for ya.

True story from one of my first pin parties:
RH: I'm gonna go play that Jacks Open
ME: Cool. Enjoy!
(90 seconds later. RH comes back)
ME: What's wrong? Someone playing it?
RH: No, I plunged the ball and I got bored before the ball made it to my flipper!

LOL.

So to repeat what others have said here. Play some and find what you like to play.

Best of luck with your search!
