Lots of very good information here!

My two bits, I have a few Honeywell Rocking Trays. These were first made for processing 8x10" color prints but are perfect for one-at-a-time 8x10 film processing with minimum (or all you wish) chemistry. All stainless so they keep developer at an even temperature in a water bath consisting of one 11x14 or 8x10 tray. Each end has a film retaining edge. There are emptying ports at each side-end for rapid chemistry change.

Today I use Unicolor rotors and tubes for daylight processing far more economical than JOBO.

Sloshers as Pere posted are really efficient for 4x5. I donated mine away.
