Despite your limited budget, it should be possible to get a good lens for that camera.
Since even new shutters cost more than that, you will have to live with something "vintage", which is a nice euphemism for "old". Almost as nice as "classic".
A "normal" focal length is about 150mm, and in that length it should also be easiest to find something good, but cheap. Look for Schneider Xenar or Symmar, Zeiss Tessar, or perhaps a 6" Serrac?
Come to think of it I might have one or more of these somewhere in my "heap of lenses". I'm in Norway, so the postage won't be too bad. I'll see what I have when I get home on Tuesday, unless someone else finds one first.
