Some other highly recommend Blue Book of Gun values but not me. I have had a subscription to Blue Book online for several years now. I am thinking of dumping them because THEY SUCK at pricing firearms. Their prices are often so far off from what the guns actually sell for as to make their pricing guide absolutely ridiculous (and that was well prior to all this frenzied buying of the last year or so). I think one of your best bets is to do an advanced search on GunBroker - which means you need a GunBroker account or can get someone with an account to run the search for you. The advanced search let's you know what particular guns have sold for over the last year. I note you said you think GunBroker prices are inflated. By using the advanced search for completed sales, you are checking on the prices at which the guns actually sold. Those prices are fact - they are not inflated asking prices - those are the prices at which they actually have been selling. That makes GunBroker's advanced search an excellent reference.I thought of gun broker but i think most prices on that site are inflated.
