Tony,
From my perspective you suffer from" excited about a bright idea syndrome" - 
I have suffered from this, as have many others have over time.We have spent 
a lot of money on things that didn't quite go the way we expected. Only to 
have someone with a slightly better/ different idea start the process over 
again.  This leaves one a little cynical, until such time things have been 
proven to work out- and generally they don't.
However we are conservatively interested in all endeavors and I have to 
admit to losing more money over a range of projects,  however I personally 
would be reluctant to invest so much money on this particular endeavor.
