So far it has performed better than my Yankee and HP combi tank, it takes 150 ml of developer my other tanks take 1 litre.

One problem I have had is the film escaping from the plastic pegs if I tip the tank over too far when emptying the chemistry.

The only snag I can see, is if I want to process colour, I will have to invent some means of maintaining temperature (any suggestions?)

The Paterson unit was designed for colour print developing. Originally it would have been supplied with a card slide-rule style calculator to help you work out presoak temperature and time, so that average process temperature was maintained. I have developed RA4 paper and its predecessor, was it called EP2 or some such.
