I've know a couple of people that were on that show and they were given the same comments everyone here in town gave them.
A) until you own the patent on the whole package, it's not a worthy investment
B) I've seen one, in a movie made over 40 years ago!
They both had snuffed the feedback and went on the Den with no further preparation. First guy was shot down due to A, second was shot down due to B. Seriously, if people around you are coming up with this stuff. the dragons are bound to as that's what they do for a living.
People always go on the fact that you should never give up, even if one person says it wont work, but at least get your act together first! LOL.
