This is a 120MB torrent download of a Vista Recovery ISO. I can't guarantee that it will work for you, but I sure have grabbed a copy for myself. (I have 2 Vista machines with Recovery Partitions, but there is something about having a physical disk that I really like.)

There are 32bit and 64bit versions.

Check it out here (recommended by PC World)
