@chrisaldrich Thank you for your extensive reply! I’ve heard of that book, maybe I’ll get it myself. Good to know that there is a lot of online support available too.

I have an Erica travel machine, although I’m not sure of the model, (it didn’t come with a manual and the machine doesn’t have any hint on it). I’m thinking about getting a Hermes Media 3, although I was really wanting a 3000, but they are really expensive here. (~$200).
