i use an AQUA FX for a 28 gallon, and it does the trick. got it from J&L for 145 bones and it brings me 245ppm down to 1.
good for a small job

I've got an aquasafe unit, I think I bought it in 2003 or thereabouts. Changed the RO on it for the first time last year (I don't know whether it needed it or not, but I did it anyways). I change out the filters about every 6 months or when I remember. DI probly gets changed yearly on it, although I bought one of those see through canisters that has the color changing resin so now I'll change it when it turns orange.

I also have an Aquasafe unit that I'm quite happy with. As long as I flush the RO membrane monthly (or so), I get regular TDS readings of 0.

I'm running an AquaFX from J&L. my TDS meter doesn't go higher than the 999 it reads off my tapwater. I paid extra for the backflush thingy which I think has probably made a difference. I have 40g rubbermaid trash bin I use for my RO/DI water and I wait till it's empty before filling it up again. Heard turning your RO/DI on and off shortens the life of the membrane.

I got a used Kent RO/DI No flush on it yet, but I am getting readings of 10 out with 700+ppm in

I've got a 5 stage SpectraPure MaxCap 180gpd. It removes chloramine, but not by using a "catalytic" carbon filter. It's removed on mine by way of the "SilicaBuster" cartridge. There's two types available. Regular "SilicaBuster" and one that also removes chloramine. It's the 5th stage. The carbon filter is a regular Johnny Average carbon filter. I love my unit. Right now, with the colder water coming in due to the season, I'm getting about 4.1 gallons/hour. But in warmer months and with new a sediment filter and carbon block, I've had as high as 5.3 gallons/hour.

HTH and cheers,
