IMO you can find something just as good as a BRS (or one of our sponsers) for alot cheaper. I bought a cheaper RO/DI housing without filters, then went high end on my filters. Remember, its the filters that are doing the job. Do your research and you can put something togerther thats just as good as a BRS or comperable for quite cheaper.
I cant remember the website I ordered my housings from, but i got my filters from BRS, made sure everything was compatible before ordering and ended up saving like $150. Yeah, my RO/DI does not say BRS on it, but Id put it up against any other RO/DI filter any day.
