First of all: invest in glass, not black boxes ....
I still have my Nikon EL2 and it works like a charm. Back to your original question: I would go for a nice F3.
Although, I would also consider the F4s. I love this camera, the way it lays in my hand, it's heavy (for me a plus)
and I just like the looks. I also have a F5 which I love also, but if I had to choose, I would take the F4s.
Both the F4s and F5 can be get cheap nowadays....
And remember Ansel Adams:
" ... avoid the common illusion that creativity depends on equipment alone ... "
(quote from his book: The Camera)
