I need to replace the igniter on my new-to-me 7-year old Accentra insert. I can get one from my local Harman dealer for $113, or I see after-market ones on Ebay for $80, shipping incl (Cdn $) ((broken link removed to http://www.ebay.com/itm/161413276971?_trksid=p2060778.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT)). I'm assuming the dealer's is a Harman igniter. The Ebay seller claims his are superior to Harman's and will last longer. Does anyone have any experience with after-market igniters? Is it worth the extra $ to buy a Harman one?
