+1 on the plume veil and the reading up on the rebuilding posts. A plume veil is real easy to build even for a new builder like me. Do lots of research. You will need a small toolbox of tools and equipment to do it safe. It is daunting when you read about it, but easy to do once you've got it down. Ohms law, battery safety and proper technique are important, even using a regulated device. Knowing the ins and outs of using a mech mod will benefit you even in the regulated world. You will understand how each build will react and why. Don't assume because you have a regulated mod (as all of mine are) that it's all safe and you don't need to know that stuff.
Now go have some fun with it, you're going to have a great time and this seems to be a natural progression for some of us.
