This is the controller I'm ordering.
I was originally going to go with the Neptune Systems Aquacontroller Jr but the DA unit looks like it's much more supported by the mfg with firmware updates and such. I almost passed on this unit as it didn't have any external outputs. However, with the latest firmware the computer interface module is now supported by the lite version. Yay! My main purpose for this is gathering the tank information to computer. I'm big into home automation and love to have things monitored for the geek factor.
