handheld Loose Leaf Vaporizers - Who uses them, and recommendations?

Looking into loose leaf vapes, there are obviously a hundred kinds made in varying places all over the globe.

I was particularly looking at the Dube and The Green Machine

Green Machine: http://milehighecig.com/portfolio/llv/
I've tried the Atmos: https://www.allstarvape.com/allstarvape-atmos_raw_black.php but that's the oil/wax one, the dry herb one is $180...

(I do not work for any of those companies, or any site, or have any affiliations)

Suggestions? Reviews? etc...

Needs to be handheld, prefer to look like a normal E-cig.
I would prefer it not to have a bright green LED on the end ... stands out from all the blue E-cigs.
Doesn't need to hold a lot, enough for 3-4 drags.
I'd like to spend <$100

I have a normal vape that I can plug into a 110v, but I want a non-butane powered portable one.
(I have one of these: http://www.allstarvape.com/essential_vaaapp_vaporizer_black.php?gclid=CO3jqbesnLkCFbAWMgodtjQARw ... it was gifted)

Apparently nobody gives a shit ..

I spent more than I intended, but I should have the PAX (legit, by Ploom) within a few days. I'll respond again once I've used it

I've used 3 vapes and I can recommend 2.

Do NOT get the iolite! The ignition system does not last and there are many complaints on the web about it.

I have had the Extreme Q and the Arizer solo and both are very solid vapes. Have not had any problems and i've had the extreme q for about 3 years now.

Hope that helps.
