I have a Speedlite 550EX for sale along with my other Canon stuff. It was purchased from KEH in bargain condition. It has a number of light scuffs, but nothing bad at all and functions great. The battery compartment it totally clean, no signs of any corrosion at all. I am asking $175 for this flash including shipping to US locations. Please contact me for shipping info outside of the US. I prefer PayPal, but if you do not use PayPal, I can take a money order etc. Please either email me using the address in APUG or send me a PM if interested. Thanks!
