Robert's answers speak for me as well. Mainly, Brian asked about less costly lenses, and he's planning to contact print, so the older lenses will do fine.

Now that I have a few 1960-70s era lenses for my 4x5", which I enlarge, I'm finding that in general I do prefer the more modern lenses for that format, because the older lenses weren't really designed to bear much enlargement and standards were just different then, but I do prefer the look of an 8x10" or 11x14" contact print made with one of my old Dagors or Heliars to an enlargement from a 4x5" neg made with a more modern lens.
