Dima,

For 120:
tank, reel(s), graduate/measuring cup, storage bottles, tupperware container*, scissors, film hangers and negative storage sleeves
film washer
developer, fixer, photoflo, and distilled water
I am not aware of these items being available as a kit, you would have to assemble them.
*to hold photflo (a few drops) in distilled water to dunk film after processing and washing before hanging to dry

4x5:
film hangers, tanks although you could tray process
chemistry as for 120
