I also like the eroll for this. But just so you know, you could get blank cartos for any of the automatic cigalikes (ie volt, blooge, blu, etc) & fill them with your own juice. Blu's battery wouldn't last you very long & isn't very powerful which is part of why some people don't like them. Not sure how long a battery on an eroll lasts before needing a charge as I always take a puff off mine & put it back in the case again. That battery is made to take a puff or 2 off it & then put it back in the case to charge. Not everyone uses it that way but that's sort of how it's designed to be used. A larger automatic stick battery might be something you'd like better. The battery would last longer. Just something to consider.
