Here's an interesting find on eBay. It's a vintage DW-5700 with a 901 module. It's started off with a "Buy It Now" price of $75 USD. It's missing the bezel though and the band doesn't look to be in good shape. The replacement parts are fairly easy to find though since it's the same aprt as the classic DW-5600. A few scratches are to be expected on something like this. Happy bidding!
