Welcome to the forum Amanda and Eric!!
Amanda, I agree with the suggestions above. Start trying everything until you find your favorite flavor and set up. Once you have your favorite flavor I highly recommend tanks, but they are not necessary. It all depends on what you are most comfortable with. If you feel comfortable jumping into tanks then I say go for it! I think they are amazing! But it is good to start out slow with a base kit. Find your favorites and then start experimenting. The only thing I would suggest getting for now is a passthrough along with a wall adapter (and a car adapter if you spend any time in the car). I LOVE my PT and use it on a daily basis, but even if you don't want to be tied down with a cord, they can come in very handy on those days when all of your batts are dead (it happens to us all ). The other thing I would suggest is to get more batteries. You can never have too many!
All of this stuff can be overwhelming at first, but hang in there. That is what we are here for Stick around, ask questions. We are here to help.
