IMO they're really there to provide the cheapest possible option for there "starting from as low as $X" marketing spiels. Of course they don't want to sell them if they can - they don't make anybody much money. Yet they do exist (and from most major manufacturers), and if you're not after the bells and whistles, they make for a reasonable investment.
