Hi Fratello,
You REALLY like those Nokia graphic LCD . . .
I think they're pretty cool too, Now as for USEFUL comments . . . According to the engineer from France who writes the Dark Side column in Circuit Cellar, . . Robert La Coste ? his suggestion is to use a PID loop to give you some Hysteresis to your temperature to prevent overshoot and undershoot of tip temp. Search the forum there is a pretty good one or more in circulation.
