When I started out I was also DI only and I trawled the internet for the cheapest resin, which I found at the time to be from Brodex. Prolite something or other, which I used for a couple of years DI only.
Meantime I upgraded to a static RO, but continued to use the prolite from Brodex.
After reading posts on here recommending Daqua who supply tulison, I switched my supply to them.
When using the prolite after RO I was changing my resin every 4-5 weeks, with the Tulison its every 3 months (we use 750l per day per vehicle).
