I'm far enough along that I have a good Idea what my cost will be.I was surprised that vaporizers (quality) are not as overpriced as I thought they were when I started.There are at least 12 headshops just on a 25mile strech of the hwy I live near and I have a good relationship with a couple of them,so I have a pretty good test market .I'm positive I can get my product on multiple store shelves after that I'll just have to see if there is a market for lower priced vaporizors with very simple natural ascetics.I'm not sure how it'll do here there isn't a huge vaping crowd in the area ,but its a low overhead project for me,I have the time and I'm willing to sell it,so the worst case senario is my friends end up with new vaporizors,best case I'll make a small profit and turn more people in my area on to vaping.Allot of people never try vaping because of the cost of getting a quality unit just to see if you like it.I'm hoping a good low priced entery level vaporizer will get more people to try it.
