It's very well made, definitely heavy (feels good and solid). The clamp is excellent. I had one attachment come with it but I suppose you can get more.
I make gnocchi too... smiles.
There are all sorts of recipes out there, but it's basically easy, once you try it out, a matter of feeding the dough into the slot, using the crank, and then changing the dial that makes the pasta thinner each time (I turn it gradually from 1 to 6, so that's 6 feeds).
I do have a drying rack that I bought and never use - my italian teacher taught us, and she had us put the strands on plastic hangers, which works fine but I end up have hangers with pasta in odd places..
You can use this to make ravioli pasta and to make potstickers (I've been playing with that) - lots of fun.
