So it's 2010 now. Who still uses a calcium reactor and who's all on 2-part dosing?

2-part for me via auto doser

I've got a low-tech doser. My phone has 4 alarms set and I dose alk and calcium an hour apart in the morning and same thing in the evening. Currently using 6mL of each. Only use Mg right now to bring my new water up to 1400.

I use both....a calcium reactor on my large tank and 2 part on my smaller tanks.
I doubt I could ever be talked into using 2 part on my large tank, I hate the mess involved, mind you I'm dosing manually.
The reactor is soooo much easier it literally is set and forget especially now that I have a bigger reactor that holds more media and I only have to fill it every 4 or 5 months
