I'm pondering (not very urgently) the question of point motors myself. Trouble is I'm not convinced that any of them are reliable. The thing that put me off Tortoises was the article (in MRJ?) a while back on how to make them reliable... basically by replacing a whole bunch of their innards. After reading that article I had hoped that Cobalt might be the answer but apparently not.
The Fulgurex motors on St Ruth have been a pain - the main issue with these is the microswitches. They are OK out of the box but soldering wires onto them tends to soften the plastic and make them go out of adjustment... which usually manifests itself as a failure at a show. Sometimes the two switches that stop the motor itself go wrong and then the motor either doesnt go or (worse) tries to keep going when it should stop and then overheats. Some of them are hideously noisy too, in spite of whatever we do to lubricate them.
Anything else? Seep? I don't think I know anyone who has used these.
Servos may offer an answer but there are *soo* many variables there - servo brand, whether what you buy is really the brand that it says on the outside, controller, mechanism to turn the rotary movement into a linear one and switching arrangements.
There is certainly less to go wrong with wire in tube straight to the facia. I may go that way but I also rather like the idea of having the controls all in one place.
Good luck at the show, whatever the layout!
