Good deals on Belly Dump Trailers?

Can anyone tell me where I might be able to find a good deal on a used Belly/Bottom dump trailer? I'm looking for specific areas or cities where the construction was high but now has slowed and there is a surplus of trailers to choose from.
Thanks.

 

Yes, I have searched truckpaper- I think that is the best site actually. I have found several that have potential and the price seems fair now I just have to figure out how to check one or two of them out. They are all very far away from home (800-1200 miles away) which is pretty far to go check out something to buy. Seller's might tell you one thing (like brakes, tire and body are all in good shape) but their idea of good and my idea of good might be very different. Pics help but its still hard to tell sometimes. I guess I just have to weigh the savings of not buying locally vs the hassle and travel expense buying far away.
