NO - IMHO - NOT A GOOD EAL . . . Ya' can find them from vendors on sale for approximately $25.00 - $30.00 for an Adept Kit, as you can a Cool Fire IV, Kroma a or Kroma R (a little better model), or even a SOLO
(got a couple for $20 each a couple of months ago) . . . And if your lucky most of them for $20.00 or less at a few vendors during a special sale or with a discount code . . . Double check in the thread's I posted earlier . . . Matter of fact, if you ask in either one of those threads and tell them what you are looking for - I am sure someone can point you in the right direct, especially the "Savvy Vape Lady" -
@JCinFLA 
. . . If she can't find what your looking for at a reasonable price then NO ONE CAN . . . Also check out the classifieds - I just recently got - well over the past couple of months - a New Adept w/Zlide Tank $25 shipped/a New Zlide Tank $18 Shipped /a couple of used Zeniths $20 shipped too
(just make sure of the ECF Members status & check their Feedback - Some people will even negotiate too
) . . . Just Sayin' . . .
For "Me" it's the 1.2 (difficult to get now) & 1.6 coils - GREAT for MTL . . . IMHO - The sub-ohms, especially the Plex coils are more then a little too much . . . Just Sayin' . . .
Oh and
@MikeE3 - I only have 400 of the Zenith/Zlide/Z-Coils, however they do last "Me" anywhere from 90+ days (and sometimes even more after being cleaned) . . .
