I have a used, at least 2nd hand CPE-2 plus, which I got probably 1.5 years ago and which has served me well. Last night I wanted to process two rolls and the thing broke. The on/off switch basically just turns freely, rather than having the characteristic "click". The fact that the lest few times it did not turn quite as easily (which I wrote off as a problem of the know rather than the switch itself) should probably have tipped me off. Oh well. Any thoughts to whether - this is repairable, realistically, for a decent cost? - who could repair it (I am a user, but ask me to solder something and I am useless)? Appreciate your answers.
