I may just buy something off of puresmoker. What's the difference between the hybrid and the classic pen style? I was under the impression that the pen style produced the best vapor.
Steve at PureSmoker will do you right-a very good supplier!
I can't speak for the hybrid - don't have one of those - but I can to the difference between the classic pens and the DSE901's - I have both.
The 901 is smaller - more like a cigarette, although a bit heavier. Batteries and cart life - limited. I could get maybe 2 hours out of my battery, and had to continually top off my cart. The draw is kinda like pulling a milkshake through a straw (such an apt description, I had to borrow it

)
My daily commute is 1 hr each way, and I had to "nurse" the 901 to get continual vapor in the car (continual meaning a few puffs, dribbling the vapor out, then one inhale) To nurse the 901 - I had to moderate my activity with it, and it would still run dry on the "home stretch."
Vapor production was ok as long as I kept the cart topped and the atomizer moist.
The classic pen (DSE801) I like better. Yes, it is heavier, and yes, it is larger. It's more like one of those fancy pens you find in over-priced office supply stores with the whopper pricetag. But, IMHO, that makes it feel more substantial.
I get better battery life off the pen, larger cart capacity, and it has a very smooth draw - it almost vapes itself. I can chain-vape for my commute, and not run dry or have the batteries blinking on me. Vapor production is HUGE - this thing smokes like a forest fire! I can vape on this all night long and top off the cart only once.... I was topping off the cart several times a night with the 901.
No matter what you try first, remember, you're not stuck with that gear forever - parts go bad, you're going to need replacement parts, and if you decide to try different gear, so be it... that's one reason we have a classified section in the forum..
