hello everyone I need a little advice I am about to buy my first rebreather a second hand classic for £1700 and am considering my options. I want a stainless frame instead of the plastic yellow one but something that's nice on the eye as well a tuff. ( i hate the look of the kent tooling frame its so ugly) Also I can't decide if to upgrade it to a vision which divers warehouse charge £2000 for or can I get the hammerhead kit (is it available in the uk) Should I get this all done before I do the Rebreather 1 course or after, and I need the classic checked before the course is that worth the money as I wish to upgrade asap. As you gather I'm a total novice and need all the advice you can give Many thanks dave
