Hi John, tnott and Patrick,
many thanks for your replies. I can see there are differing opinions on some of these issues. So, in order to start on this road, the first step as I see it is some sort of multi-output heater controller.
Tnott mentions an Astrosystems unit, - but does anyone recommend another brand/model for some reason?
Many thanks for your time and trouble taken to reply guys, I really appreciate the info. Some of KR's gift money can go on this, so it's my duty to spend wisely.
Don't suppose any of these items are Aussie made are they? If so I would check those out first.
Cheers
