So it's 69 bucks, my apologies.

On a tangential note, dude that username is, woof

I use this one and it works just fine. AQUATICLIFE Aquatic Life RO... https://www.amazon.com/dp/B00204CQF6?ref=ppx_pop_mob_ap_share

I use a RO buddie 4 stage and it works very well though a bit slow at producing RODI
i also bought a extra carbon stage to add on along with eventually upgrading each section of it to a new bigger stage container when they run out
also there's the exact same or similar water pressure and tds meters on BRS you can get on amazon for cheaper

I picked up this for $59, but I leave off the deionization. It brings my sodium down to 20ppm and bicarbonate to 25ppm. I don't worry too much about chlorine because of the boil. It may be an issue with sparging, but I haven't noticed yet.

I originally bought a chlorine filter and used it with my ward's water report but upgraded to this: https://www.amazon.com/Aquatic-Life-Changing-Deionization-Cartridge/dp/B00204CQF6/ref=sr\_1\_2?crid=35D1AD3MP6ZWV&keywords=ro+buddie&qid=1666261953&qu=eyJxc2MiOiIyLjU3IiwicXNhIjoiMy4xMSIsInFzcCI6IjMuMDIifQ%3D%3D&sprefix=ro%2Caps%2C104&sr=8-2&ufe=app\_do%3Aamzn1.fos.18ed3cb5-28d5-4975-8bc7-93deae8f9840
