Purchased new from premium aquatics last October. I traded my rk elite for this after the guy had it for a week. Had to send the base unit in for replacement in december/january and they replaced it with a new one. I want $450, with shipping and insurance included. Since I have owned both high end controllers I'll give my opinion, that I definitely prefer the apex over the rk elite. This is still under neptunes limited warranty as well.  Apex System Contents    1 Apex Base Unit    1 Temperature Probe    1 Apex Display Module w/ 10’ AquaBus cable    1 EnergyBar 8    1 6’ AquaBus cable    1 Standard Grade pH probe    1 Owner’s Manual By [url2='n30hydra':3e3jll17]n30hydra[/url2:3e3jll17] at 2011-05-07
