Low resistance atties are most useful when used with a mechanical device to get a warmer vape out of the non-boosted battery. However, with a VV or VW device that boosts battery power output, a standard resistance atty will give you the widest selection of power choices.
Digital Cigz has
Joyetech 510 Atomizer 5-Pack (2.3ohm) for $14.95. Use the coupon code VAPELAUNCH to bring the price down to $11.96. That's a really good price for genuine Joye atties.
I've not been a fan of cheap atties including the Joyes. I find the flavor and overall performance to be noticeably better with
Cisco spec atties. If you like the Cisco spec try the HH.357 which is even better. The price seems high but Hanna will refurbish them for a reasonable price as long as you don't pop the coil or weld the coils together with gunk.
