Ditto. My pool was white capping. I got the Pool Pilot Digital 220 with the 36 cell. I can't relly judge the performance of it as I just hooked it up last week. It is a real nice unit and very user friendly. I think retail was around $1800. I found it online for $899 plus shipping. My pool builder picked it up somewhere and sold it to me for $1000 including installation. Couldn't beat that. One of the nice things about it is that there is a Pool Pilot expert (hi Sean), and many others with Pool Pilot knowledge who frequent this board and are extremly helpful.
