I'm looking for an aquarium controller for $150 or less. I know it's a limited budget but figured an old RKE, Archon, AquaController, or even an RKL if that's all I can get. May also consider a Seneye so I can test my PAR. I want to be able to monitor temp & salinity while able to control a few things so if the unit is ready to go to do this, that would be ideal. Let me know what you have, send pics, and your asking price. TIA
