I shouldn't speak for Justin, as I may have this wrong ... but as I see it, the essential difference is that he is not selling gaskets as a profit-making enterprise. Instead, he developed the original gasket for his own TR4, and started selling them to others more or less as a favor to the community. The 6-cylinder version was only by "popular demand" (although I suspect he was considering owning one) and took a long, long time to come to fruition.
IOW, it's a hobby, not a business.
Of course, the other difference is that he has no competition. There simply is no place else you can buy anything even remotely similar. I daresay your business is not in the same situation /bcforum/images/%%GRAEMLIN_URL%%/grin.gif
