we are in the process of buying a short sale property with viking bank involved.  the deal has not closed yet, but so far  I have nothing but praise for how they handled everything. response to offer within 48 hours.  we got our mortgage through the same bank also to take advantage of financing incentives and again they were very responsive to our concerns and willing to work with us to find an arrangement mutually acceptable. 

not that you can really choose which bank you deal with in the matter of short sales, but I would highly recommend viking bank
