Just read your post, I have to say I sell cameras and your preference with Canon is defo justified, may I suggest you have a look on Go Industry DoveBid, if your not in a rush then take a look on there, I myself used towork in the scientific sector in additon to setting up international auctions with the sciences, as you can imagine I came across alot of weird and wonderful items. The reason I mentioned the above is from time to time I came across top end cameras so it is worth keeping an eye out. Hope you find what you are looking for. All the best Bazzatc
