There was a very good deal on these, but all out of stock, but if you don't mind waiting awhile... very nice mod/tank for carry around. The mod is very simple (3 voltage settings) but comes with a subohm tank (good carry around) it's still a great deal:

Also, other options for simple devices... even some "pod" like ones. I won't use my good gear for carry around... not worth risking it.
