I picked up a 1D MkIII at a pretty good price recently. Everything included but the AC Adapter/DC Coupler. Not a big deal, but since I would like to have a complete kit, I started looking for a used unit. B&H had a used one for $69. rated 9+. I had it in my cart and ready to pull the trigger when I decided to check KEH. Found KEH had 2 units for $23. each rated EX. Now, I've purchased used lenses from KEH before and had pretty good luck, but for $23. I figure this adapter is beat to heck, but it is what it is....so I order it.
Unit came today......flawless...not a mark, looks brand new and works perfectly. Considering these go for around $98. new.....I'm good!
