Digital BW, The Print

Is there any other paper that is similar to Kodak ultima satin in 
terms of its printing characteristics.
I have used the kodak ultima satin and I am pleased with it. The only 
limitation is that it comes only in one size 8.5x11. I would like to 
be able print on a larger paper similar to Kodak satin.
Furthermore, if anybody knows where I purchase a bigger size of the 
Kodak satin paper, please pass it on to me off the list.
