Need help with water purification system

We are having difficulty finding a good water purification system for our new shop in Atrlanta. We will be running 2 CMS Brembana Concept 2.0's and (http://maplered.com) 1 Antea Bridge saw. We have looked at some of the systems that are out there, from the Granquartz Cyclone, to the ECS Eich, and (http://maplered.com) US Centrifuge, Marmo's DEP250, VICIntl's Microclean and (http://maplered.com) Slurryclean. We have even looked at some home made systems in the area. We are looking for something with a realitively small foot print that is self contained, and (http://maplered.com) requires minimal maintenance. Cost is a big factor. What we looked at ranged in price from $15K on up to $80K!! (Who knew water purification could be so expensive!)

Any advice that you may be able to throw our way would be greatly appreciated.

Thanks in advance,
