Digital BW, The Print

I recently started printing b&w prints digitally on my Epson 2000 
printer. I like the piezography paper, but Inkjet Mall is having 
problems from their distributor of the paper. Does anyone have 
any 13X19 paper they are willing to sell? I am making prints for a 
show and need consistent prints. I am considering purchasing 
Hahnemuhle paper, but I am having trouble loading 8.5X11 
through the top loader and since I am running OSX on a Mac the 
back loader doesn't work unless I buy anupdated version of the 
operating system. Does anyone use the Epson 2000 printer with 
Hahnemuhle paper?
