Welcome. My advice to you: Go slow. I dove in and now I have so many back ups that I could have just bought a real
mod, and have been done with it.
Of course, once you get your perfect set up, there will be something better right in front of you. Don't
buy any new equipment until you get yourself verified and check out the CoOps and Classifieds. I jumped in with both feet, and now see that I could have saved a ton by being patient.
Aside from that... congratulations on making the switch to a healthier lifestyle. You should see results from your change very soon.
