I have a couple of relatives who work for companies that make medical devices too.
I'm sure they could make some really nice devices, if they wanted to do so.
We are still in the beginning stages of what vaping is going to become.
I'm thinking they will be sold like Bic lighters.
If you want a fancy vaporizer, you could buy a Zippo or Colibri PV...
I think you're right that that someday -- and that someday won't be long... these things will be mass-produced and sold like Bics and Zippos. Overall, that's going to be good for the whole concept of vaping. Anyone will be able to walk into any store and buy a high-quality mod for a relatively few bucks.
Still, something will be lost... the idea of some guy sitting down in his workshop and saying, "I think I've got a better idea," and working it out. Of course, those of us who bought these mods now will own genuine collectibles. Something like when rare pipes come up for sale... Not long ago, I checked out the site of a place that sells fine used pipes (they call them "estate pipes")... the prices of some of those make the prices of today's best e-cig mods seem like pocket change.
