found this: its a 403 in a wood case, for $30, at https://cincinnati.craigslist.org/msg/4719903731.html quoted: This thing has been sitting here for a bit. Very unique part of the Casiotone series, all wood case, and really nice feeling keys. Needs a nice cleaning to get everything up and working how it should-some of the key contacts are dirty underneath-that's why I'm letting it go for 30 OBO instead of the 150 they go for on eBay. Perfect candidate for circuit bending or pounding out triads in your St. Vincent-esque band.
