Generally I prefer sub-ohm tanks, are there any on the market currently that don’t require mesh coils?
Sure there is...a good selection of them, too. Here's just a little info. on 3 of them: One of my friends loves the
GeekVape Cerberus sub-ohm tanks, and there are many different coils, even by different brands [GeekVape, Eleaf, SMOK, etc.] that are compatible with the tank. Another friend and her husband love the
Vaporesso NRG and NRG-S sub-ohm tanks. Same thing, as far as there being many different coils that are compatible with those 2 also. There are definitely other sub-ohm tanks, too, that don't use only mesh coils. Those are just 3 I'm familiar with.
There are actually quite a few reputable US vendors who
are still selling and shipping vaping gear and supplies. Some of them are: KangerWholesaleUSA.com [they sell to retail buyers as well as wholesale to vendors], CentralVapors.com [linked below, has
the best price for the Vaporesso NRG-S tanks in the US - $15.99], Ejuices.com, VaporAuthority.com, DirectVapor.com, MyVaporStore.com, Breazy.com, EcigMafia.com, VapeSourcing.com [a vendor in China, but they have a US Warehouse, too], InnokinStore.com [they ship from a US location they have, too], and many others. I've purchased from 5 of the above, in just the last couple months, and I've gotten good-great delivery time from all 5.
In case you want to check out the Vaporesso NRG-S tank at Central Vapors:
VAPORESSO NRG-S Sub Ohm Tank - available in a lot of colors
Coils for them:
VAPORESSO GT Replacement Coils - There are 5 different GT coils to choose from, that aren't mesh. A few friends like the GT2 - 0.4ohm and the GT Cell-2 0.3ohm coils. Again though, there are other brands of coils that are compatible with the tank.
Not every vendor ships to all 50 states, but if they don't...there will usually be a notification posted of which states they can and cannot ship to.
