I can't help with brands because I'm on the other side of the pond and I don't know what you can get over there.

My recommendation would naturally be a heavy metal machine with a solid clamp, but moreover, one that has an automated roller. Some machines have an automated attachment that you clip into where the crank handle goes. That keeps the rollers rolling at a decent speed and allows you two hands to deal with the pasta.

That usually isn't enough in any event.

Dealing with kids and making pasta; two events where an extra pair of hands would be so very helpful!
