Welcome Walk Tall.
What equipment is good is kinda personal and depends what you want it for. Most want to give up analogs for health reasons and your 'no-name' might do this for you, some just like vaping and want their own personal steam engines, so they get big expensive PV's. Note that all e-cigs are essentially 'no-name' devices from China until someone puts their own brand name on them, mostly to push up the price. W.r.t local manufacture, forget it, won't happen.
I HAD to stop smoking, but liked the idea of doing it in a 'smoking' kind of way by continuing to suck on something that produced a goodly amount of 'smoke', gave me nicotine when I inhaled it and a 'smoking-like' feeling in my throat and chest. E-cigs worked beyond my most optimistic expectations!
Yes, PV's are temperamental, but you'll soon learn to keep them going and 1 device with a few spare atomisers and batteries, and a good supply of liquids in the fridge, should maintain continuity and keep the analogs at bay. What's caught me out before is having 1 device but no spare atty, having only 1 battery charged and ready and, needing liquid and having to wait 3 weeks for my dealer to get my preferred liquid from China. Shouldn't take you long to figure this out and be prepared.
You being in Margate probably means you must depend on online purchases so sure, you will need a reliable supplier, or you can also order direct from China. W.r.t. China, read up about Chinese suppliers on this and the main forum to establish which to trust. For local SA dealers, be cautious, the e-cig's potential for a quick buck has created a potential for many fly-by-nights. My recommendation for a 110% reliable supplier and good prices is Cig-E who doesn't sell direct but through a series of dealers which can be found here:
Cig-E You have the option of emailing him if his suppliers let you down and I'm sure he'll fix it.
Good luck.
