As Tim says most of the above SLRs are fine for the purpose you want.
Shop around and don't worry about buying an older model as they don't change a lot from year to year, and I doubt if you could tell the difference between the actual photos. Don't forget the bit that sticks out the front is probably more important than the box on the back ! PM me if you buy an older Canon and have problems.
PS I've got a brownie 127 if you want to make me an offer.
