The catalytic lighters that I like can be a pain to shop for, especially if they are used, because you "can't" repair them if the platinum filaments or platinum-black ball(s) are broken or worn out. You can always tell on ebay when someone is trying to dump a crappy one, because you won't be looking at any clear pics of the exciter sub-assembly, or whatever it is called. You can swap that whole exciter sub-assembly out with another lighter, which is handy if you have a beater case with good filaments, and vice-versa. Usually you can find NIB New Methods with the box and the glass extra fuel vial & cork on ebay for $40 to $50 total, and it should be in "near-mint+" condition for that price. Someone just sold a sweet store display with 10 NIB lighters included. 99% sure that there's someone on here who has a box of 20 or 30 of them, he was selling them off a while back.
