www.anitec.ca has some w3520's. http://www.anitec.ca/product/012967/...*d0_stepping*/ I called and they 4 left (3 now!) . A little pricey but I jumped on it because I didn't want to roll the dice on a 920 or have to wait months for a steady supply of D0 here in Canada.

Edit: they only ship to Canada!
