A decent RO/DI unit?

I was peepin out this unit
5 Stage Reverse Osmosis Deionization System Bulk Reef Supply
and am considering getting one in a few months after i save up for one. I am sick of going to the store to get buckets-o-water and think that i would save money in the long run to just get a filter.

Is the above one a decent one?

If not which others w/o spending a fortune on a top of the line one?

Thanks reefeers!

 

well i think and im sure other would agree , 3/4/5 stage units are very good.
But remember the filter membrains do the work inside RO/DI units , not how pretty the unit it it's self.
I have to change mine out every 6 months ( i change out all 3 in mine )
but that loks like a nice unit to me.

 

Thanks wildreef
