I believe you are referring to the Aquarium Pharmaceuticals "Tap Water Purifier". There are some of Jack Watley's discus fish on the box.
Check out: www.thatpetplace.com Go to the fish icon. Look at the fish product index and select:
RO & Deion units. The TWP is one of the first listed. It runs around $25-$30. I ran one for years. Great for a small tank where you have modest water needs.

Thanks for the info, that's the one i was looking for.
Oh No...dont do it man... I had one of those for a while and its a hassle no matter how you look at it. The filter cartridge dosnt last very long at all. I was using it on a 38 gallon tank. I always had algae and my water quality wasnt always that good. Then one day I opened my eyes and saw the light. I bought an ro/di water filter. After that the problems gradually went away and I started to have better water quality. If you do buy it, do it as a temporary system till you can afford a ro/di unit. Oh well later man and good luck....
I guess it's mostly dependent on the quality of your input water.
They can last a long time on a small tank if you have very soft good quality water to start off with. If your water is not good to start off with then a TWP is probably not the best choice.
It's possible to recharge the resin for next to nothing. Instructions on how to do this are easy to find on the net. Just watch that you take care with the chemicals used to recharge the resin as they are very strong.
Darkreignn, I know a lot of hobbyists using RO/DI and still have excessive algae problems. Conversly, I also know of many tanks using the tap water purifier with no problem.
I think it's just a case of the state of maturity of each system as opposed to which purification method being used.
Every tank I have set up has gone through the algae stages until they mature.
I am one who has no problem using the Tap Water Purifier and my tanks seem to work out just fine.
