DOES ANYONE USE A RUN STAND?

I use water because it doesn't get devilish cold here and if I have a leak, I'm not wasting coolant. Also, 50/50 is bullshit. I'm not paying for half water. If it was half the cost of 100% I might but it's always close to the 100% coolant price.
I buy pure ethylene glycol, and a jug of distilled water from the grocery store. Mix it myself, and it's close to half the price of premixed.
