Cool, both of us should make it this time. Working down in Lawton on some stuff for a little while but will make sure to try and be off for the meeting. I was just doing some research on RO/DI systems actually made a rough comparison for cost of using RO/DI water vs buying distilled or RO water from one of the store refill systems.
Usage is based on gallons used per month. RO/DI also includes the cost of tap water used with waste and approx cartridge costs.

I was kinda bored as at the time I was still stuck at home not feeling the best.
http://nacl-h2o.ventshop.net/node/27 shows some of my views on the whole deal and how I see it. And yes you can get refill water for .25 per gallon there is a BYOB water store that has two vending machines outside and 4 inside that sell water for a quarter. I also believe that .37 per gallon is an average rate for refill at local grocery stores. The actual cost of water for a gallon new varies greatly but the example should be pretty close.
