Ok...I have to let you guys know that it is my company(s) that holds the worlds supply of Mercury Flame Safety Switches. I was buying them back after my post in 2008 in anticipation of everyones stock depleting. Now here I am in 2010 with a bunch left and looking to sell. Yes my companies have them listed for $500 each which may seem expensive relative to the cost 2-3 years ago but what do you charge for the last parts IN THE WORLD?! I offer a reasonably priced alternative to replacing the fireplace ($2500 for R&R). I am sure my competitors have told their customers that the part is not available when they know I have them. I try to provide customers with options so they can make an informed decision on repair or replacement. Please review my contact info if you need to reach me.
