A few posts (or pages) back in this thread there was talk about the Ijoy SRDA, which has a pre-built deck with coils permanently installed, and you screw that into the base. You only have to re-wick it when the cotton goes bad, and you can buy the decks individually when the coils eventually go bad (months), and IIRC it has an 810 drip tip, but you can get an 810-to-510 drip tip adapter for a few dollars if it does not come with one, and then put any 510 drip tip on it.
I think that is likely the only way to squonk without actually building or installing coils.
Otherwise you can buy pre-wrapped coils from places like Lightning Vapes, Advanced Vape Supply, Pure Coils, and then you have to install and tweak them into the RDA, and cut the leads, and also wick/re-wick them.
So maybe look at the Ijoy SRDA and see if that will work:

Also, you should watch some YT videos on how it works, like from Daniel DJLSB and Tony B from 'The Vapor Trail Channel' to get an idea of what it will take to keep using this atomizer.
DISCLAIMER: I've never used one of these and build my own coils, so I cannot speak from experience, but I thought this item would be really for a niche market like for people with motor-skill problems etc..
EDIT: Also, AVOID getting the Ijoy CAPO kit that comes with the 100W squonk mod, since it only gets to 100W if you will build your own coils (around 0.17 Ohm) and only has a circuit to BUCK the voltage from the battery and not BOOST the voltage, so it works as a protected mech mod, similar to the Pico Squeeze or Luxotic BF, and since he is going to be limited to the coil decks offered by iJoy, and whatever resistance they come out to, there really is no comtrol of the output on that Ijoy CAPO 100W squonk mod.
You can do a lot better with a fully regulated squonker like the RSQ, Hcigar VT Inbox v3, or Pulse 80w, and also the new Pico Squeeze 2, where they will in fact allow you to boost the battery voltage..
