Martin I have a sauce maker probably similar to yours It is called Roma sauce Maker with a few different screens and is motorized spits out seeds and skin in one end and sauce the other makes life easy is right. It can accept attachments also but all I seen for it is fresh pasta attachment.
I like Pizza, spaghetti, macaroni , Ravioli, manicotti. linguine, alfredo,vermicelli, cork screw, lasagna, ziti and well I just like it all. lol
Yes the San Marzano and also Opalka tomato are good for sauce the Opalka is another heirloom from Poland I believe similar to SM The Opalka is more productive for me and resists white fly better it seems
Do you make your own sausage? I bet that it is good, that I have not made YET!
Rafed Yes the only way is to try
Here is a San Marzano I just picked not ripe yet but i wanted to show a picture
