I bought this insert new from B&H last summer and used it once. Since then I've thinned out the gear somewhat and a smaller bag is fine. The insert is in like new condition. For more details, here is B&H's description and current pricing $39.99 plus shipping at B&H. I used with the Canon 1Ds3 and a couple lenses. The other 1/2 of the bag had a small medium format kit in it.

My price is $25 shipped and paypal'd in the US. This is a US sale only. The picture below is the actual insert for sale.
