Another one to look at would be the wismec luxotic bf kit. I purchased it with the tobinho for around 35 as my first squonker. It has some protection i believe so not unregulated. I couldnt get along with the tobinho rda so order a wasp nano and its been my go to setup for a few months now. Ive recently ordered a new mod and manta rta to try out but both have remained in theor boxes still as im enjoying my wismec so much i cba to set the manta up for now
