Aquadyne octopus 4000 controller

[NaClH2Okpr]

Does anyone have experience with the Aquadyne Octopus controllers 3000 or 4000?? I have been looking at the 4000 online but want to make sure that it is good before I spend that kind of money on a controller. Are they relatively easy to set up? reliable? easy to connect to a PC?? Probes good or bad??
Any help would be greatly appreciated..

Thanks
