That's right Aaron! He of course would not go into detail and I didn't ask. I can't remember for sure but I think I did ask him if he patented any of the parts and I think he said no.

 

Patents I would bet get expensive? I have no idea but then again if their units cost x? Imagine if patents etc...the cost could go up exponentially or just put a fella out of business.pretty sad.

Maybe some day I will save the scratch to get a good unit for mine.
