Poets and quants just put out a great article summarizing all of the top us 1 year programs http://poetsandquants.com/2012/07/10/gu ... -programs/
I have the USnews compass, and its nice to have. You can compare schools, and grab useful info about each school all in one place. I dont know how helpful it would be for someone specifically looking for 1 year programs though.
The good news is, there arent many of them, SO, search the sites of all the schools covered in that poetandquats article, and dive a bit deeper for more info and stats on the 1 year programs specifically.
