Good Price for a 1991?

I'm in the market for a Colt .45 and have decided to get a 1991.
There is a gun show this weekend and I'm planning on looking around for some 1991's. What would be a decent price range to look for on a blued 1991 used and/or new?
I know gun show prices are usually high just plan on looking around for some possible deals and would like to know a good price range.
Thanks for any advice.

I haven't checked them lately, but Bud used to be a really good baseline for prices IMO.
