Are there any general observations that one can make about the market for used basses like Englehardt, Christopher, Shen, and Upton that sold new in the $1000-$3000 range? With popular mass-produced guitars you can pretty quickly check online new and used prices and figure out the typical markdown. (Used price is usually 55-80% of new depending on make and model.) Basses are a smaller market with relatively fewer online sales. Can any of you who have watched it closely for a long time describe your impressions of how the prices of decent factory laminates and hybrids like the ones mentioned above?
