My PB is also planning to use the easytouch 4 system with the intellichlor swcg. My PB is basically using all Pentair products. I believe the easytouch line is a bit cheaper in cost than the newer Pentair intellitouch system. The 8 way system will be great for all your water features, etc. I have not heard pros/cons against other controllers.

The handheld controller itself does seem a little big for what it does but thats not a big concern to me.
