Been using the Caravel as my espresso machine of choice for a while now and it is becoming part of my morning routine. Fast warm up is a big plus. The fiddly little filter basket is still an irritation. I need a funnel. Easy temperature adjustment is good, but I really want to add a PID, partly because I can, partly because I like a temperature display. I find I am naturally compensating for variations in extraction rate by adjusting pressure on the lever, don't know if other lever users do this, but it definitely reduces incidence of sink shots. Probably also reduces number of God shots, but I enjoy the coffee so don't mind.
