I realy with I can have a game room, I currently have a great Mame
cabinet that I built and S.t.u.n. runner but women just don't understand
how us guys feel when we see an old cabinet we use to play in our
childhood so I will never be allowed to fill up a room with the machines
I want, I have to settle for the little corner that I have in my garage.

But, If I did have the choice of a couple machines, they would be:

1-Zwackery
2-Sinistar
3-Lumber Jack
4-Jungle King
5-Disc of Tron
6-Time Soldiers
7-Bomber Jack
I'll stop there.. there's too many and my head hurts.
It's strange because I can play all those games on my Mame cabinet but
it's just so much better to know that you actualy own the original.

1-Zwackery.... forget it. 12 in existence... any of them go for 3000$US...
2-Sinistar...   I have a Duramold project!  
3-Lumber Jack... never heard of it
4-Jungle King... good one, not that rare.
5-Disc of Tron.... I have a converted enviro... Ya never know...
6-Time Soldiers...  I know Newf112 picked one up from Amusement911.
7-Bomber Jack... Mighty BombJack you mean? always a favorite...

Zwackery and DOT are the pricey ones on your list...
