We had a White Mountain Freezer for AGES and the motor broke when it was dropped.  Since there was a cheap (and I DO mean CHEAP) little Rival machine on sale for a mere $13, we decided we would try it - what could it hurt?  Well, so much for icky soft-serve.  It was just useless.  When you put the "finished product" (and I use the term loosely) in the freezer, it froze solidly and you couldn't scoop it out.
