My recommendation, since you've never had it before, go with just the 1oz tin, that way you don't have too much if you end up not liking it.
And for the milk or lemon question: Milk.
Personally my taste is just a dash of milk (or cream), no sugar needed, but I rather like strong teas.
And if you do end up getting the Caravan and you don't like it, just send me a pm, I'm sure i could be convinced to take it off your hands for you.
