I'm looking at a PRS custom 24 with the 5 way rotary switch, bird inlays, and the thin/wide neck. How cheap have you guys seen these babys go for?

new or used?

used, doesn't have to be a 10 top either

13-1400 is probably a realistic price though you might be able to find something closer to 1200. That would be for a post-'95 instrument that's not particularly recent, either (e.g., '96-'00).
The thing I hate about these questions is that people see posts like mine and think that anything over 1200 is a rip-off. The truth is that there are often reasons for the lower price such as dings, unpopular colors, or highly motivated sellers. The fact of the matter is that 1500 isn't outrageous, especially if it's a popular color in very good condition. Finally, there are seasonal variations in the used gear market that can influence the price that a given item will fetch.

By seasons, do you mean like Trent Reznor just picked up a JC Penny fake strat, so their going to be popular? Or do you mean seasons like times of the year when people just arent buying guitars?
