Origin V2 (clone) was my first, followed by Magma (clone). Both are easy to build, great flavor, both have been really good to me. I use my Magma away from home, the threaded top cap makes it great for a pocket build. I prefer the Origin aesthetically, so it stays at home where I can admire it, sitting on top of my Mutant V2.
As you're getting started, I have to say - be patient, try new builds, experiment with wicking - the latter is probably the most important aspect of a build. You might not get mind-blowing flavor first time, but it'll come when you figure out what you're looking for in a vape.
