I would agree with Keith. However, it seems that people are asking a LOT more nowadays for instruments that a short while ago (as in September/October) were going for reasonable prices. As others have indicated, an individual sees something listed on Ebay for several thousand dollars more than it could really fetch and prices their instrument accordingly never looking back to see if the instrument in question actually sold. I recently made an offer on a Series I that I though was quite reasonable given no DS-5 power supply or cable was included and it had not had an electronics upgrade but never even heard back from the guy with a counter offer. I suggested he ask for feedback here as to what the going price would be for a bass of this type but I don't think he ever followed through.
