I'd guess there are a fair number of reefers in my position. Incremental purchases... I bought a RKL Basic to run heater and lights, bought an extra PB4 to extend it a bit, add an SLX and a pH probe... RKL is full. If I want to do any more automation, I have to upgrade to either RKE... which would allow me more modules, but not necessarily remote alarm capabilities. Yeah, I've seen the net module, but everybody pans it in reviews. If I want online alarm capabilities, from where I'm at, the Archon would seem to be the way to go. If they're having problems with them, well, I'm not looking to add instability
Which is why I was asking BRS. You don't carry them, has to be a reason why.
