Well, depending on what you are going for the RSST comes in a dual coil Pyrex tank version for pretty cheap, and it's simple to set up, relatively. It's a lot simpler if you don't dual coil it and just get the single coil version. I got a Pyrex tanked RSST for ten bucks, threw a .7 ohm build on it with a 400 mesh wick and was vaping happy right away, but that might not be your thing....
