I think you’ll find that it is £609 in Calumet and thats €760 at the moment.
In fairness this is a secondhand camera and it appears that there is no warranty on it. Yes there are 2 extra batteries and a 6GB card but its a gamble. I’m looking for a 40D myself, if there was a warranty with this i would go for it. But without a warranty it would need to be seriously cheap. Did you get it in the states?
I have had the 20D, 30D and 40D and never a days trouble with any of them. They are very well made and don’t give any trouble unless you expect it to perform outside of it’s parameters i.e. 300K Shutter Actuations, Sahara sand, Treating it roughly etc.
