After a lengthy period of flying into airports where go-arounds have been few and far between, I have recently been operating out of an airfield where they are much more common, due to weather and airfield facilities. It has rather focussed my mind on this subject.
I am a bit sceptical about the statement that a go-around to 1500' should not use a great deal. I suppose it depends what you mean by a great deal. But on the last three occasions (with a 737) it was between 600 and 700 kilos. Given the need to declare an emergency at 1200 kilos, or rather more pertinently if you believe you will land with less than 1200 kilos, obviously there is not a lot of margin.
You would have to be pretty brave (some might say foolhardy) to take minimum fuel under these circumstances, as I am sure most if not all would agree. The more interesting question is how much is then enough? If a go-around is a distinct possibility I favour taking enough to try an approach and then have enough to divert and land with some options left.
