I equate these types of strainers to the KitchenAid meat grinder attachment.
I know a lot of people here have them but a good motor operated one is by far better.
As fanatical as some folks are about tomatoes and such it has amazed me more folks dont have them.
Even at $10 a month in 5 years a person could save up $600 for a very nice tomato processor.
Even then this is more than a good one costs.
Not trying to insult anyone that has bought them at all.
I just know how many years (34) I messed with a little hand crank meat grinder.
