There are many places on the Web to buy Spaetzle-making products. You may even find a ricer in your local kitchen store. Just be sure to rinse the sticky dough-covered utensil with COLD water right after use. This will aid in cleaning it.
To be honest, I haven't ordered any products from these companies. I will update you with my experiences as I do so.
