By any means your not talking cheap as rebuildable coil, a rebuildable coil has a variety of factors whether you can call it cheap, I'd disagree, the liquid id say cheap, but dependant on coil type and liquid consumption of coil ,power, whether going single or dual or whatever preferred, a spool of 20-22 or 28 if you prefer mtl for straight round wire builds, I'd agree could be cheap to run, but soon you start looking at custom built coils prices can whack up quite significantly! Than individual needs to learn to maintain & clean complex coils to get best life out them which can be quite a lengthy process in itself especially in certain complex coils like interlocking alien, tsuka, mohawks and things like that, whether it's a squonk mod rather irrelevant, even companies made squonk like mod system based on premade coils , IE. Kangertech Dripbox, aspire revvo (had round wire plate in an rdta and Vandy vape did something similar I think with the maze), grimm green dead or undead goat RDA was a premade round wire coils cartridge
