Actually, yeah they are. the elite without NET was $349, I got it for christmas from my b/f.
The net module would allow you to monitor your tank from any internet connected computer and even shut things on and off. Very nifty, but it runs another $100 for that option so I passed.
each powerstrip comes with 4 outlets and the basic elite kit comes with 2 of them, so you can control 8 devices straight away. I had to buy a third strip since I have sooo many devices and gear. They run I believe about $80 each. You can monitor ph and temp right out of the box but salinity is another module for like $70 and a probe. The temp and ph probe are included by the way. Check out bulk reef supply or aquacave, they have the owner manuals and everything so you can really see what they can do. bulk reef supply even has a you tube video of them setting it up and programming it. It made it soo easy for me just watching that video plus it gave me ideas. The video should be on their website, if you can't find it i can look for it.
They do have a competing controller, the apex as well. I price compared though and it came out like $150 more for the same options so I went with the cheaper one.
there's so many options with the RKL, you need to look one up and see. lol I plan on adding a moonlighting module at some point too, it plugs right in and comes with little led pods
that you can stick or mount anywhere and you can adjust them to ramp up and down. Like $70 for it too, much cheaper and easier than me finding moonlighting for a six foot tank. lol
