Ok, this is what I was thinking. I took the intelligencia coffee course in new york city. (It was cool too.) In any case, I played with a fancy, latest issue marzocca machine and it had a feature which timed the shots automatically as soon as you clicked on the group head pump. When you'd click it again the timer would stop. It was so useful! I loved it compared with my set up where I have to remember to push both the timer and the group head button at the same time. So in any case, I am considering desiging something like this for the la spaziale... :-)
