I also think the Eos Elan7/33 is a good choice, but its viewfinder isn't the best.
The Eos 5/A2 is older and command dial may be easily broken if you don't care; it's a problem with this camera ; but its viewfinder is excellent.
I also have a 3 but I don't use it : it has not internal dioptric adjustment and I don't need 45 focusing points...

If you only use manual focus, you'll prefer the 1N, with a better viewfinder.
