If...
I were you I'd just check Ebay and CraigsList regularly. Most of the people on here that would have one will either be collectors that won't want to get rid of the machine, or the machine will be incomplete or in horrid shape. Oh and a tip for Ebay look for the Destiny and only search for "Kenmore Destiny" when looking less people know/think to check for one thus you get less crazy fanatics bidding. Most people also don't know what they have thus they list them way less than the Lightning. A perfect example is what was just on Ebay. A Lightning for $50 plus about $20 shipping covered in about 2 inches of dust, cord rewind doesn't work, and it comes with nothing not even a hose. Then there is a Destiny 3000 it has some light scratches and scuffs from normal use, a hose, and the cord winder works. The Destiny is only $9.95 plus $21 something shipping total came out to $31 and some change.
