Good for you Ade! You'll find you very quickly recoup what you spend out if you collect anything British, especially medals. Also helps save a few pennies on dud purchases. The basic package is normally adequate for most things and if you get stuck, just ask as I have the premium one so can do any extra look-ups. I pay for it monthly as it's a little less painful.
I should make it clear that I am heavily involved with genealogical research as well as medal collecting and as such sit on an international panel as the "military research adviser". Thus these sort of research projects are a passion. My own 10-year book project is about 5 years in and I'm hoping that I'm on target for completion 5 years hence!
