You might want to look at this: $11.04 SXK Krma Styled RDA Rebuildable Dripping Atomizer - 316 stainless steel / 22mm diameter / w/ BF pin at FastTech - Free Shipping
Use fasttech and it takes 50% off; $5.52 with free shipping for a high flavor, pretty leak resistant, rda is decent.
To convert for non-squonking use, on the underside of the rda there's a small hole with an Allen screw in it. The rda comes with the Allen wrench of the right size. Remove the little Allen screw and put in into the hole in the 510 connector (it's threaded to take that plug).
I placed a ft order I hope this is the last gear order I have way to much vape gear nic and flavors that will probably out last meI am behind, so I'm guessing you've received some replies already.
I would take a serious look at the Dvarw MTL FL. $16.83 Dvarw MTL FL Styled RTA Rebuildable Tank Atomizer - 5ml (22*19.5mm (OD*ID)) / w/ 10*air inserts / stainless steel + glass / 22mm diameter at FastTech - Free Shipping
That one comes with 10 different AF inserts so you can choose the one that suits you best (proper MTL to airy).
I have a Dvarw MTL FL and installed the 2x2.0mm AF insert which is the most airy. It's a lovely MTL. Dvarw's are known for their great flavor. They are easy to build on and maintain.
Others I would recommend would be the Kayfun lite 2019 (22mm and 24mm) and the Tripod. I have those and they're excellent. FT also sells both.
Hope that helps.
ETA: added links for the last two
