The Paterson Orbital had the option of a manual or a motorised base, but unfortunately, it is no longer in production.
I second the Paterson Oribital - sadly only available on the used market. Once load in complete darkness the rest can be carried out in ordinary room lighting. Continuous agitation is required and as said 1 to 4 sheets of 4x5, 2 sheets 5x7 or 1 sheet of 8x10 can be processed in a small amount of chemistry.
