I've got a Valentine One (latest version) with a concealed display unit for sale. I have all the boxes and accessories (somehow I lost the manual, but it's downloadable anyway). It's in like new condition, only used a few times over the last few years.
Email me for pics at firstname.lastname@example.org if you are interested. I'm looking for $400 including shipping and insurance anywhere in the continental U.S. I can take Paypal, but will only ship to a verified address.
