Which equipment should I buy first the Tunze Osmolator 3155 ($170) or the BRS RO/DI 75GPD ($140), both on Black Friday special. I currently purchase from my LFS 15 gallons of water every two weeks and is 10 minutes from my house. Probably the most practical equipment is the RO/DI unit but the ATO will also make my life easier since TO is an everyday job.
Thanks
