So from what I gather, I too want an RO setup, the more stages and filters you use the more the ph will drift downward. I think the cheat code here is to only use the R/o filter and not all the other filters. Aiming for 30-50 ppm for a more neutral ph that doesn't drifts as hard and pure 0 ppm can. I guess the more oxygen 0ppm water gets, the more it can drift downward or become acidic. I think that little bit of ppm actually helps us by preventing that drift. I just don't have the experience to say if this is good practice. Just my current understanding. This is the setup I am looking into buying. Hoping someone could point out what I'm overlooking.

I have the money to get more stages but i think it may just add more unnecessary work. Hoping to learn enough from someone who does now so I can just buy this thing or something similar.
