I own three different firearm reference books/pricing guides: the Blue Book of Gun Values; the Standard Catalog of Smith & Wesson; and the Gun Traders Guide. I find them to be very helpful in researching a possible purchase. My question is does anyone utilize such a guide to establish their asking price on the ODT? This is not another thread to beat a dead horse regarding high gun prices. I think using a guide should take some of the emotion out of the process and resulting in a fair price to both the seller and buyer. Any thoughts about how best to arrive at a reasonable price?
