More stages is not necesarily better, it can actually be worse as each stage has an associated headloss which reduces the RO membrane efficiency.
You do want 4 good reef quality stages though, not ebay quality and not Air Water & Ice. I owned their Typhoon III previously and would not recomend it, the filters are too coarse, it uses a second unneeded carbon and other things like a fixed flow restrictor and prepackaged DI resin. You can do much better for less money and it will end up costing even less to own and operate over its lifespan. I do recommend Spectrapure which has a good reef quality RO/DI for $125 right now as well as Buckeye Field Supply and PurelyH2o. All sell good quality systems using good filters and components at good prices.

I have the Spectrapure 4 stage Ro/Di. I believe RO/DI is a must.
I have been using a bulkreefsupply 4 stage for years, love it! super easy to get filters and replacement parts for as well.
