Which Dosing Pump for 2-Part

[Horace]

I am looking to buy a 2-part dosing pump. I dont want an IV pump that I have to reset every other day either (some do that for some reason). Im looking to dose Randy's two part with one pump for my SPS tank. I think this will be cheaper than running a Ca reactor and perhaps even a bit easier to adjust when it needs it. Please recommend a good pump...Thx!!!
