Blue book value is useless & allmost always does not reflect a true resale value.
If you want to know the (current) resale value you can do a few things,the 1st would be to pay attention to ebay & audiogon listings,especially audiogon,the 2nd thing is if you can afford to spend a few bucks,subscribe to the Audiogon bluebook service,it will show you all the last sales of your model & what they sold for.
Demand,supply & desireability are what set a resale price ,not a book only used by pawn shops.
