I doubt the $50 vapes are worth dealing with. Most want the heating element and nearby attachment assemblies to be clear from harmful emissions. They make ceramic encased heating elements that don't touch glass parts that end up vaporizing your herb. I like seeing blurbs like glass-on-glass, and ceramic/glass coated heater element, etc. Also, there are two main things that control the temp of your load, and I think it's wise to carefully consider both. (1)The entire heating system, and (2)the user controlled amount of relatively cold incoming air. It's commonly said that digital heater control is better than analogue, and most seem to like the option of filling collection bags if they so desire.
Anyone tried the following yet? Not sure it's feasible, but to me it sounds like a good idea.
How about (1)starting off with a half decent looking, not bulky, economical and safe heating element vaporizer. Then (2)carefully modify it to accept some forced air from (3)a fish tank style pump or PC type blower fan for "powered shotgun" or "power assist" mode. With (a)enough air pressure and (b)hot enough heating element, you could even fill collection bags!!! It would be awesome turning 150 bucks worth, into something that most charge 300 and 400+!
I believe that by including some variable speed forced air, you get two benefits.
-More reliable and efficient vapor flow produces more consistent and controlled vapes
-Vapor party bags! DIY standard/giant economical (clear trashcan) capture bags
