After learning to correctly tray develop in a Michael Smith and Paula Chamlee seminar I have not looked back because you can develop any sized sheet film in trays with absolute consistency on par with any rotary methods. I do multiple sheets of 12x20, 8x20, 11x14 and 8x10 in trays and it is a day at the beach for me. I have learn to accept that some folks just are not conditioned to work with trays and that is just fine. But there are no moving parts that need replacement or service with trays.
