Fellow Tower Talkians: Any suggestions for a high wattage soldering iron good for using on PL259s (100 watts or so??)? Most of the 25-40 watt irons found in the mass hardware places (Home Depot/Lowes) seem to melt more die-electric than solder. Anyone use/have any luck with opne of those Sears 100/400 watt soldering gun? Tom, WW5L
