Anyone have any good reliable cigar lighters to suggest? I prefer the blue flame butane lighters. Have gone thru so many that have either needed frequent repair due to unclogging etc,( Colibri's), or just plainly don't work any more. I've tried cleaning them by air blasting and unclogging by bleeding them...most still die after a while. Are there any reliable cigar lighters that will continue to work for years, or do all of them have a limited half-life?
