Hi LG,

The "Money Tree" was a Brian Blackwell System from some years back.

I,ve got it here somewhere.

The others I,ve never heard of.

Cheers

ps.Barry Watsons system (Came 3rd in the Aust Systems competition run by PPM some years ago) is the best I,ve seen.Still going strong all these years since.
As has Winston Charles adaption of the original Dark Horse.
