Are you familiar with the MFLB? Because it's not like modern battery powered portables, it used shitty weak batteries, without a button even, I had the old Thermovape T1 instead, which was great but sort of like a convection version, a weak point being the awful batteries, because back then battery tech was really lacking and now it's come a long way thanks to the e-cig stuff!
Yeah so MFLB is purely conduction, heating the herbs directly from the steel mesh, on regulated based off of the charge level on your batteries, it's a game and it's just really old not polished tech especially even for the modern artisan scene of wood vapes today...
So there's really a wide variety of options, the TM is really the best, they still are going to sell the TM1 so it will be available a little cheaper, the TM2 is just all around better made, fit and finish among other minor upgrades, but the TM1 had rolling upgrades as well and I never felt like my OG was lacking before, it was already my favorite most versatile vape ever!
There are a lot more options, wood artisan style, unregulated requiring technique in a way similar to the MFLB (like vapman with a torch that was mentioned) and 510 mod convection vapes (like Dreamwood Glow or Milliken Shammer) but the TM is more of the first mass produced more mainstream fully regulated pure convection on demand artisan style vape...
The budget end has come a long way too, with the Healthy Rips brand session portable vapes, and xmax v3pro and xlux roffu too (these two are on demand convection) if you want to save money and try a more modern vape experience... I find they don't have the best flavor compared to the more expensive artisan scene however (makes sense since they focus more on simple pure materials and often have glass chamber and pathway, what I love about something like the TM, is how many options there are for that, I like to use with aftermarket glass stems and WPA with dry glass like a hook for best vapor quality)
Hope this helps! There's really a lot to catch up on
