Last fall I bought a classic in 300 H&H that was NIB for $650 and consider myself lucky. I later saw them for $750 on up for used rifles!
Condition, locale, and rarity -- some newer Classic calibers are for sale all the time, but many of the older ones are less commonly on offer -- all factor into price. With internet sales, however, regional differences in asking prices are bound to narrow in my opinion.
The classic is one hell of a rifle and well worth the money. I would not give Walmart their asking prices for the newer 700s unless I ws going to use it as donor action.
