Sean,
First let me say that I sell PoolPilots where I work and it is our top of the line brand, We also sell Zodiac and Resilience SWG's (Used to sell PoolEx but that is a whole other story!) but when people ask about getting a SWG tell them the only one to consider is the PoolPilot!

My biggest problem is that I don't know enough about them to help my customers who own them adjust them, particularly cell output and the frequency of cell polarity reversal. I guess I need to download the manuals if they are availble on the website and study them! The Digital is a bit more complicated that the other units I am familiar with. I do most of the water testing so I am the one that has to help them adjust their chlorine levels and such.

I own an Aqualogic PS-8 and I chose it over the PoolPilot Digital for the automation, plain and simple. I am able to maintain separate cell output for pool only /spillover mode and spa only mode with the unit so I am able to keep the spa at about 2 ppm higher than the pool to compensate for smaller water volume, higher bather load, and higher temp and it seems to work out fine. I have never needed to shock either the pool or the spa since the system went online last November. I only run the spillover when adjusting chemicals or if I want to impress company with the waterfall so I can keep the heat in the spa. Normally I have an 8 hour pump run time on the pool and 1.5 hours on the spa daily. The spa is on a countdown timer when selected manually (a function of the automation). The Aquarite cannot do this, it is automation in the Aqualogic that allows me to do this.

You are correct about having to adjust the cell output in the Goldline units with changes in temperature but that is easy enough to do...just requires testing and monitoring the FC levels which should be done on a regular basis anyway and then making a small adjustment to the output of the cell! Also the salt readout on my Goldline units is usually about 100 ppm higher than on a calibrated Goldline salt meter and MyronL salt meter, and from what I understand the unit is not able to be recalibrated like the PoolPillot against a known correct reading
