Had autopilot dig 200 for 32,000 gallon in ground pool for about 7 years. Top of the line tech when installed it. Great when it works. Have replaced cell three times at almost $400 a pop. Now nead to replace master controller. $599 for replacing it or $899 for new one with all the parts. Heard there are now other options. Looking at the hayward
D aqua plus. Any thoughts? Long term cost and maintenance is the issue. Not the up front cost. Thank you.
