Less than $200. I say it like that as most kits are $150 but you may need adapters, tubing etc. Buckeye is a great source for RO/DI. Their units don't really comes as a kit, you'll need to make sure and order the appropriate adapters. It's the idea that since everyone's needs are different, you can keep the cost down a few dollars by not including every adapter.
