The DMR-ES40V, if its still otherwise functional, might bring in $25-$40 through a Craig's List sale. Listing is free. If you have a digital camera adding a photo is easy enough.
The VXY1867 model DVD Drive used in the ES40 is the same as used in other 2005 model year Panasonics. (The models with hard drives may use a different model DVD Drive.) Due to its bugs and design flaws my ES40 has had little use (around 355 recording hours) since I purchased it new in December 2005. I keep the ES40 primarily as a parts source for the four heavily used 2005 DMR-ES30V models in our household. One of those ES30 models has more than 4,600 recording hours; another has around 3,200 recording hours with the other two not quite so heavily used.
