On the RO/DI, more $ , IMO, does not make BETTER water. I myself have a BRS 5 stage, 75gpd unit. It was $190 new but I got a deal on it used on line for $100. My point is, if you use a TDS meter, and 0 TDS water is being made, then that is ALL you'll ever get, 0 TDS water. You cannot get PURER then 0 TDS and spending MORE $ on say a 6 stage isn't going to get you ANY better water. For your size tank, a 50 gpd ro/di unit is MORE than sufficent. The only thing additional filter canisters will do, perhaps, is make the time between having to change the filters longer. For instance, running TWO DI units won't get you purer water then running 1 but it will make the 2nd DI resin last longer but big deal. Just run one and have a pouch of DI resin for backup. I HIGHLY recommend the BRS 5 stage plus system for about 190 to 200. It has built in 2 way TDS meter (going on and coming out). It has built in flush valve and very high quality fittings. I am NOT connected to BRS in ANY way but since I heard of them on this forum I buy a lot from them because items are HIGH quality, service is awesome and prices are FAIR.
