Actual Cig look and feel was my TOP concern as well. Thus I ended up going with an L88b model. It is sold at Blucig.com, volcanoecigs.com, and 3domecigs.com (freedom ePack); all interchangable with each other; exact same size as a 'King' Analog Cigarette.
ModernVapor.com also sells the SideSho, which is the same as the L88b model, but with a longer battery and more personal customer service. Lots of sellers for the L88b and compatible models, so you end up with quite the selection of LED colors.
However, the L88b model seems to be quite disliked amongst the serious vaporers, especially on this forum, so many L88b lovers stay quiet. The reason seems to be due to the limited vapor production, short battery life, and shipping/PCC problems Blu, the first L88b seller, had some time ago.
I have a 510, but it is just too darn heavy for on-the-go use, I have to prime puff it before taking an inhale, and my cheeks get tired of sucking so hard after a while (L88b draw is easy like you are sucking through a straw). But it is a vapor beast and I look like a steam engine when I use it.
I haven't tried the Revolver Elite yet, but I want to after I learn more about its compatibility with other models and after they've had a chance to work out some of the PCC issues some users have been experiencing.
If you do go with the L88b model, and if you enjoy heavy Marlboro Red style cigs, I suggest you also buy some 306a atomizers (rockymountainvapor.com sells them) since it fits
perfectly and produces more vapor and a stronger throat hit.
L88b PCC is great because it lets you fit 5 fully assembled carts and atomizers, along with one fully assembled e-cig. That lets you keep the same flavor for each atomizer, gives 6 available cart/attys for long trips between refilling them, and lets you pull the e-cig out for immediate puffing.
Ok, sorry everyone for the L88b love. Please resume the regularly scheduled 510 love fest.
