Bernie,
Hemmings is a very good site to get a line on the prices of any type of car, but they tend to list most of them a little higher than you can actually get one for. You might try looking up some of the larger Mustang Clubs as they have For Sale Forums just like we have here on CC. A 65/66 Mustang is almost impossible to buy in this area as the few around are either really all out show cars and not for sale or have been bought up to clone the GT-350s.
Good luck with the hunt and I believe prices will continue to drop for a while as more people lost their jobs. I have been trying to get a guy that I know who restored a 65 to sell it to me for two years and he is still holding out but not quite so stubborn about talking about selling it now.
