Where was this one purchased?

I bought two from Amazon.com and the first one is on my Xfire and no problems at this point; I can't say that the stabilizer made much difference but certainly no worse; I think that is just an indication that my original was still in good condition........of course I have kept that original one for possible future re-installation if needed. Also would be nice to have the original one 50 years from now.........that would be a rarity.........LOL!
