We've been exploring food mills since my wife broke the one that attached to the stand-mixer. I started a thread about them here:

In this process, we decided that we wanted to go with the Squeezo brand mill. My wife bought one on ebay and when she found it was missing the fine screen, bought another. New, they're about $250 and there's a several-month backorder (which is only getting uglier with new tariffs, I imagine). We paid $90 and $100 for our two sets and then compiled one complete set (to keep) using all the best parts.
If someone wants the set that remains, we'd be happy to sell it for $70 plus shipping. It seems fine and comes with the coarse and medium screens, one original gasket and two home-made (cut from silicon sheet). It doesn't come with a manual (though it isn't rocket science) and you can have the one original box we have, for improved storage, but it will probably cost a little more to ship.
Let me know if you have any questions.
And you can go check out the opportunity to buy them new here:
