hmmm...part of me is concerned about trying to give someone with a bit of a background in photography a system for $1,000. I hope your friend is prepared for this just being the first $1,000 of many to come .

First thought was to look at B&H used department for a 50D. I didn't find anything, but that changes all of the time.

My other thought would be the 85 mm f/1.8. It is going for $389 right now and could make a nice pair to a rebel with the kit lens.
