Looking for an RTA

Hey everyone,
I tried a friends RTA for the first time and am interested in purchasing one to learn how to wick my own coils. I wouldn't want to build the coil itself but just wick the cotton. Any good beginner tanks in mind capable of high wattage and user friendly? I would be using it on my Smok G150, currently running the big baby beast but since it came in a kit it doesn't have the RBA section :( looks like I need a whole new tank.
