Do you want a hand-crank or an extruder machine? For roller-style machines, Marcato or Imperia are good choices. Available parts (for now!), reasonable cost, well-made in Italy. They both have a range of machines, Imperia tends toward more restaurant-sized and motorized machines. I've used both, but I have an Imperia hand-crank now because I got a killer deal on the machine and a bunch of attachments. If I had to buy one now at full price, I'd get the Marcato and all the attachments I wanted. Machine is around $100, attachments are $30-$50.
We had an extruder machine that someone gave us, don't remember the brand but I really didn't like it. Loud, lots of little parts to lose, long assembly/cleaning with those numerous little parts that get lost
, and really finicky with the texture of the dough. There was a really fine line between dough that was too wet and too dry. Too dry would strain the machine and make "fuzzy" pasta, too wet made globby noodles that broke on the drying stand more often than not. The crank machine makes great round pasta like spaghetti, and is far more tolerant of dough texture. For ravioli, I wouldn't recommend the machine attachment, but the "plate" style ravioli makers that you run the roller over the mold to crimp and cut them. I use molds that I 3-D printed, because I can scale the print to make the size I want, and since they cost about 50 cents in material, I can have a few of them to make large batches.
If you have a Kitchenaid mixer, they do sell a pasta attachment for it, but it costs about the same as the Marcato machine.
