Posted last week about my dig 220. Seems like the cell needed replacing, but before I ordered it, the dig unit itself now appears to be shot as well (display is stuck, and is unresponsive to any input I attempt). I am now having second thoughts about continuing to use this system, even though I know others on this site really like it. In truth, it has given me a lot of trouble over the last few years, and it is expensive, so I'm thinking about other options. A comparison chart I have seen may well be slanted to push certain brands, so I'm wondering if the Circupool RJ60 or the Compupool CPSC48 in your opinions, might be more reasonable alternatives for my 44,000 gallon pool. I also know some people that have used an Autoclor system on their pools and are very happy with them, would this be another option as well? Thanks for any advice.
