I just use a pair of cheapo IGO-W Plus RDAs. They arent anything fancy(no tank or adjustable air flow or anything like that), and I am sure there is A LOT better out there, but for only being about 11 bucks a pop, I can't complain. They give you the options to run single coil, dual coil, triple coil(i would assume so, anyway), and even quad coil I drilled out the air holes to 3mm and love it. Again, I am sure this is far from the best setup, but I am more than happy with it. There is a lot of room to work with. For a beginner, I would say it is great. If it craps out on me in a few months, I won't really be upset or lose any sleep over it. After all, it was only about 11 bucks. I ordered two of them from a vendor, a pack of 80 sheets of japanese cotton and 100ft rolls of kanthal in 24, 26, 28, and 30 gauge from another place. Haven't looked back since. The only problem I have run into is that I will probably need more 26 gauge kanthal, since I have been using the crap out of it trying all different coil types to find the most flavor.
