Just wanted to throw this one out there, for those who did not know. Canon has the 5d MarkII on the list and are selling the refurb to you for a little over $1600. I just talked with them a couple of days ago.
So if you have a old 10D with a error99 you can upgrade to the 5dMarkII for 1600 which is a lot cheaper then they are going for used right now and you are getting a short warranty with it as well.
Just thought I would put it out there.
