Check out this ebayer http://www.ebay.com/sch/5448johnd/m....&_trksid=p3686 he has an $18 CA53 for a BIN price of $145 and a $40 DW5600E for a BIN of $125. I think you have to admire the cheek of the man. "Very hard to find", yeah if you don't leave your house, switch off your internet and don't accept mail order catalogues, extremely hard to find! "Vintage NOS" I wasn't aware that vintage was used to describe something 2 weeks old, you learn something everyday.
I'm gonna mess with the guys head by sending him little questions like whether he has the original Casio dealer papers with the compulsory, signed collectors certificate or the stainless steel, numbered plaque that usually comes with the CA523 or the gold plated, signed by "Ibe", original numbered certificate that usually accompanies the DW5600E, I mean there have only been half a million sold, I need to know I'm not bidding on just an ordinary everyday DW5600E like the other 5 million pre illuminator models.
