Just ordered the IC40 with power center from ebay for $715 shipped. The guy who is going to install it said he spoke with the Pentair rep about compatibility with Aquarite. Sounds like the rep was pushing hard for me getting the IC40. Said something about it being "self cleaning". And something about having to reprogram the intellitouch to make it likely work with aquarite.

On a side note. Some guy on ebay is selling an IC50 (cell only). Maybe its a prototype?
