RO system

what would be a good price for a RO system? And which brand would be good?
I seen a few on amazon for around $300. Is that a good price one? Or do you have one that you use that like that would recommend?

i have robudy system https://www.amazon.com/dp/B00204CQF6/ref=twister_B00DV4370M?_encoding=UTF8&psc=1

so far been working great been using it about 2 months now from 150 ppm to 0. I Have it on a 14 gallon barrel for my veg closet. and going to t in my blumat rez soon. the di container is filling up faster then i thought it would but bulk replacement is cheep.

replacement cartridges are about 30 for all 3.

Check out the Growonix GX200

I’ll definitely check out these two brands! Thanks for the quick responses!

WECO makes some badass filters. I use one of their 350 GPD units. Love it.
