I purchased a Purely H20 unit. Price is excellent and they are better than some of the others because they come with the 1 micron pre- filters.

Vertex Deluxe 100gpd RODI is a very good unit for the price. If your tank is only 7 days old, I would consider getting a cleaning crew first.

I bagged a BWI SR1A 75gpd system last April. They've recently become a sponsor on the site here and I believe they have a sale on right now. Very good system, comparable to any of the US vendors and no hassles with customs, brokerage fees etc.

I really like my AquaFX 4 stage RO/DI. Good quality design. Mine is 50 gpd, and I think it's a bit slow for a 90 gallon tank (it was a great choice for the 33 gallon tank I had when I bought the RO/DI). I'm getting close to needing to replace the RO membrane so I will upgrade to a 150 gpd membrane and flow restrictor. Be aware that 100 gpd membranes are not as efficient as 50 or 150 gpd membranes, and won't lower your TDS as much as the others which in turn will wear out your DI resin quicker.
