I don't remember the post, but I buy my tenants Cascade Complete powder, Jet dry rinse aid, and Finish dishwasher salt. It's an inexpensive combination, cleans and drys excellently, I don't have to repair the common complaints or issues with pods.

I also use the same combo at home. Only need to fill the salt reservoir and rinse aid quarterly, or as needed, and a half teaspoon of detergent in the prewash, 1-1.5 tsps of detergent in the main wash.
