I am sure dozens of others have already answered, but here goes.
Not saying I am going that way, but I have questions ....
1) Has to be some kind of newfangled electronic chip involved. So it means don't drop it, or get it wet, or use in high-dust environments, and so on ?
Will be the same as any other mod with a circuit board inside it. How durable it is will depend on the enclosure, not the board.
2) I am guessing there are several TC mods. What would be the better electronic chip ?
Evolv DNA chips are the best (made in Ohio), but there are some very good boards out there from China.
3) Who makes the most durable TC Mods ?
Tough to say. There's tons of TC mods out there. Pretty much every regulated mod has TC these days.
4) I am an M-T-L Vaper who stays around 10 or 11 watts. Is there TC mods for my style of vaping ?
TC can work for any style of vaping. All it does is estimate the temp of the coil and keep it steady throughout the duration of the draw.
5) I prefer squonking over tanks. Is there such a thing as a Bottom-Feed TC Mod ? (and who makes them ?)
Yep, you can find squonkers. I know there are DNA squonkers out there.
6) I build my own coils, not a problem here. But I have to use something other than A-1 Kanthal ?
No you cannot use Kanthal. It's not a big deal, though, because stainless steel (316) feels almost the same as Kanthal when building. It's just as easy to wrap and build with.
7) Would I need a new atomizer, or could I use, say... a Chalice III ?
Atty doesn't matter. All that matters is the type of wire.
8) Can I still choose my wattage preferences even at lower temperatures ?
Yes. However, the mod will adjust the wattage down if you go over your temp setting. Depending on how "hot" you've vaped in the past, you might notice a bit of a cooler vape depending on your temp setting.
9) Don't take this the wrong way, but can I stay under $300 ?
You can get a good TC mod for $50. If you want to go with the best (DNA), you will likely end up around $100-$200 depending on the mod you choose.
So, a quality water and dust resistant TC Mod (preferably a squonker) that would be good for a Renaissance Vaper (dislike the term Tootle Puffer) for a decent price (but not cheap).
Quality and Durability mean more than lowest price available to me.
Go with a DNA squonk box, then. They are out there.
Maybe I should just stay with my dinosaur gear. I am happy there....
Nothing wrong with that, but at the same time, TC vaping will make you as safe as possible as far as avoiding the nasties that form at high temps. And you'll never again get a dry hit even with an empty tank.
