Seed trays from Park Seed. Cheap, effective, develop 6 or more at a time...6 is about right, but I have done as many as 8. Develop by inspection if you would like too. That's what I do. Check out my website if you like. All done with pyro and DBI in trays. Properly done, you won't get scratches either - even using efke. Consider taking a workshop by Michael and Paula for Development by Inpsection and contact printing too. You can also jobo it, as I have a jobo, but don't use it anymore. I could do two at a time.
