I was wondering what everybody considers to be the best choice for soldering irons in use today. I'm looking to find out make and model, variable temperature, wattage and why you prefer this iron over others. Mine is on the way out and need to buy a new one. It was a 20W/40W iron which I believe had many brand names and was handed down to me by my father many years ago. What temperature is a good choice for most electronic work.
