I have used rotary development most of the time for many years, first with a uniroller and drum, and for the past 15-20 years mostly a Jobo.
If you want to try rotary development without the expense of a Jobo, look for a Uniroller, or other roller base which reverses, and a Chromega drum. These drums don't leak or depend on a gasket like the Uicolor drum.
An 8x10 wil do one sheet, naturally, and a 16X20 will hold 4 sheets of 8x10. Only the amount of chemistry to fully develop the negative is needed so developer quantities are minimal.
The system works very well. Sometimes I use it if only doing one or two sheets of 8x10 and don't wish to get the Jobo down off the shelf.
