I have made pasta many times! My pasta roller is from the thrift store - after Christmas there just may be a few donated in your area!! Go check - it is worth it.
First of all - my disclaimer, I am completely self taught and my pasta is not perfect, but it is a lot better than the dried imo.
After you make the dough (just beat an egg slightly, add it a little olive oil and a bit of salt to the flour until you get a dough), it is important to then rest the dough so that the gluten can form. I give it about a half hour. Then I cut it into pieces, roll them in flour and begin to crank it through the machine, getting thinner and thinner as I go.
Homemade lasagna noodles are the best thing I make, but the spaghetti and also good.
