You're going to enjoy the M201 immensely - by far the best I use (although I still use the 510 when I'm waiting for a battery to charge!). Kinda like a grown-up 510 as it gives great, warm vapor, and a reasonable throat hit. It's just a great experience.
The biggest knock is how sensitive the batteries are to noise. Recently went to California on a plane and while I started with fully charged batts by the time we landed the batteries were all but dead. Gonna have to find a soundproof package for them next time!
