		does a controller really save any maintenance time? What are the advantages. I think I would be better offwith a controller rather than spending on a chiller i only use two months of the year. How easy/hard are they to use? I have read lots of manuals and product pages but would be interested in hearing form people who actually use tnem. I never see them for sale used. Does this mean everyone who buys them never sells them or no one really uses them? hope i am not breaching some ettiquette here by jumping someones topic. Just curious.
