I too have a spare 4x5 enlarger, an older Omega D2, in storage that I'd happily give to somebody who would use it. I bought a newer Omega D2-V some years ago and the old one has been in storage since.

As for how to develop 4x5 film, I recommend doing them one at a time in the Paterson system 4 tank - no hair toys needed - just make sure to use the center column and put the film in the tank emulsion side in. Save and search for a Jobo expert drum and a unicolor motor base..it is very well worth the expense.
