Hey George,
Like Casper, I'm a Canon man, although if I had a Nikon, I wouldn't be complaining, as they're both fine camera companies. Did you have a lens in mind to go with your camera? The canon 350D is a good solid workhorse of a camera from what I have read so you couldn't go wrong with it.
Just ensure if you buy one, that it still has some life left in it shutter wise. A lens will cost you between £100 to £200 for a good one, such as 75-300mm I believe Casper has which seems to produce some pretty crystal clear shots, he must've got a good copy of the lens!
Any ideas where you had hoped to buy the camera?
