My Canon 1D Mark II digital SLR body is up for auction at eBay. The shutter was replaced 13 months ago and only has approximately 7,000 actuations. 10% of the sale price goes to Sea Shepherd Conservation Society.
It was my 2nd camera (1Ds2 was primary), and has had much less use. It's in great condition!
The donation option that eBay now has is great! They credit your donation toward sale fees, in effect subsidizing your donation. Of course, I suppose my decision to support Sea Shepherd will preclude whalers, shark finners, and seal clubbers from bidding on my camera. But that's ok with me.
