Kind of looking for an inexpensive rda to try out, I currently use an Istick 30 with Kanger Subtank nano- I don't really want to get into coil building (not yet anyway), because I don't have the patience and I don't think my hands are steady enough, I will probably use pre-built coils. I think I will be fine wicking and replacing coils though. I would like something with open airflow/ easy to draw on, I really like my Subtank nano with the air control wide open. Even more airflow might be nice.

I tried a tester rda at a local B&m, and of course I forgot what it was, but it was like trying to suck a golf ball through a garden hose. Only had two small air holes and no adjustment. Needs to be able to run .5 ohm coils, and run on my Istick 30w, as it's all I currently have, and I really don't want to get into mech mods- I'd mess something up and it would blow up or catch fire, guaranteed (lol). Just wanting to try something different. Thanks in advance for any advice!
Not sure what price range is inexpensive to you, but here is what I came up with.
Splitting it into 2 groups Authentic and Clone/Replica/etc
Authentic
Freakshow or Freakshow Mini by Wotofo/A-Mod
Tri post design is a slightly more difficult to build on, but its not too bad. The Freakshow will offer a little more room vertically other than that they are the same. Air flow can be adjusted for both dual and single coil builds.
I have the mini, its a great little RDA, plus you can't beat the price.
$20-30 (
VaporDNA (Sub Ohm branded)/
Eciggity/
Kidney Puncher)
Mutation X V4 by Indulgence
Quad post design will be easy to work on, plus the V4 has alot of airflow options. Again the price point is there.
$30-35 (
VaporDNA (Sub Ohm branded)/
Eciggity/
Kidney Puncher)
CLT V1 V2 or V3
Oldie but goody, this was one of the first cheap authentic RDAs. The later versions had a much higher airflow and I think V1 and V2 were quad post and V3 went with a tri post design.
$20-35 (
VaporDNA (Sub Ohm branded)/
Kidney Puncher)
Mako by Beyond Vape
Another tri post RDA with decent airflow.
$32 (
Beyond Vape)
Tugboat V1 by Flawless
Good tri post RDA thats on sale for $35 directly from Flawless. In colors and comes with a drip tip`
$35 (
Flawless)
Clones/Replicas
Pretty much every Authentic I mentioned has been cloned and can by found online, sites like
Fasttech/
Angelcig/
eBay. They usually run $7-15 on said sites.
I will mention 1 clone that I started with:
Magma V1
Easy to build single coils, a little harder a for dual coil. Airflow is a little restrictive, but not bad. I usually build a single 0.5 ohm coil but open both air holes up.
~$13 (
Fasttech)
