Monty, thats an affordabel system for sure, but to be honest i think if you get that one you are gonna wish you had a few things, like a pressure gauge and an auto shut off valve. Also, i don't know about those horizontal DI canisters, ive always heard that vertical ones are alot better. If i were you i would save up for the OCEAN REEF + 1 FIVE STAGE 75 GPD RO/DI, its got all the things you are gonna buy for that other system down the road. Gotta love that inline TDS meter.....
IMO keep saving and get the good one, until then ill hook you up with water.
