Concur wholeheartedly with drduc.
A local dealer has a Springfield sporter that started off that way - not as an 03A3 - with a Shilen rebarrel to 25-06, asking $325, nice overall shape. Been sitting there for months. You couldn't buy the barrel for that. In the shops I see any number of sporterized Springfields and Mausers for $300 and under, often with wood that couldn't be bought (today) for the asking price. Lots of model 12s, too, but the ones that are moving are either properly priced (lower than a couple years ago) or collector quality.
It seems the stuff that's moving at "decent" (for the seller) prices are ex-military 1911A1s, M1 carbines (CMP seems to be out of them), and the like. Their prices seem solid. I don't really follow the black gun market, so I can't speak to that, other than to note that it seems that's what the younger shooters want.
As to the stuff on gunbroker, GA and GI, there are guns there that have been there at least 2 1/2 years and will continue to be there until the sellers come off their idea that people have enough money to pay their prices.
