Dude Derek, it is well worth it. Despite having to change filters, some as often as 2-3 months (like your sediment filter, 5-8 bucks), WELL worth it. Just buy some bulk DI resin and store it in your freezer. Keep your DI resin packed, and swap your sediment filter every other, other, time you go to the LFS. You can unfreeze and rinse all of your foods in it as well. That will keep your phosphates lowwwwwwwww.
