anyone know where to get DI resin for a refillable cartridge? I'm looking for best price (assuming all DI resins are of equal quality.)
Thanks in advance.

Re: DI resin
The problem is not all resins are of equal quality. Some resins will remove silica and some will not. Some DI setups will rapidly exhaust the anion portion of a mixed bed (due to CO2 in the supply water) and some will not.
I use a specialized resin, because polyphosphosous is put in Rockford's water to ensure that iron remains in solution. This polyphosphorous goes right through a RO unit and can exhaust the normal DI resin rapidly. Also, non-indicating resin lasts 2-3x as long as color indicating in my experience.
So, be careful in assuming all resins are equal.
That being said, there was a recent group buy offer from resin depot (resindepot.com) I believe, look in CMAS forum for the thread. I buy my resin from Spectrapure, because of the issues I described above. Much more $ than normal resin initially, but worth it when performance and cartridge life expectancy are figured in.
