I recommend going with a more conventional mech and 510 dripper first.
The issue with hybrid mods in my experience is that they are designed to only be used with the dripper that was made for them. So if you choose to get a kayfun or something at a later stage you won't be able to use it with the dreadnaught.
Vapeking.co.za has a nice selection of good quality clone mods, atomizers and batteries that are reasonably priced. @Stroodlepuff and @Gizmo are always happy to help, and you won't have to wait a month to receive it either.
Thanks, will take a look at their options........
