Wow, £140 for an orbital, I bought two (separately) for less than that together and then paid a further £35 for a motorised base (never actually used it).

I have found that 400ml is more than sufficient to cover 4x 4x5 or 2x 5x7. To agitate I lift one end of the Orbital slightly to rock it in the water bath.
Apart from the Jobo Expert tanks, sheet films processed in the Orbital are as good as they get, no scratches, streaks or other blemishes.
