Is anyone interested in my alkatronic? $400. Going to try the mindstream which is vastly more expensive (1k plus $500/year disks) but I do love trying new things out.... New alkatronic are $900 and I will toss in quite a bit of the concentrated reagent that I have left ($110 for full bottle) plus pH calibration bottles. I also have replacement tubing for the pumps. Everything is working great. According to the Facebook page they are pushing out a sweet new update soon too, check it out.
