Well, given the two responses to your question here, coupled with the amount of literature available in the public domain at your disposal, I guess you're just going to have to make that decision for yourself.
I've got nothing for sale, and I'm certainly not getting involved in any competition, I don't have the desire nor inclination to do so, so I don't give a hoot one way or tuther.
But I'll take the liberty of saying this, you'll be searching for the truth 'til the cows come home.
