Epson Archival Matte, is a fairly inexpensive paper for daily "proofing", and in my opinion it looks pretty good for it's price. Apparently it's not free from acid etc. so in reality not so good for Archival use, but since this is not the issue here, I'd give it a shot. I do indeed have a pack that I use for testing/proofing, and for the real deal, I use Hahnemuhle Photo Rag and Moab Entrada...
Have a look at some of the satin/luster/pearl papers too, if you want prints that are not for framing, these types of papers are pretty astonishing. Examples; Canson Infinity Photosatin, Epson Premium Luster, Ilford Galerie Smooth Pearl, all three are quite different but really useful to have in your arsenal as a complement to Matte papers. For non Matte "proofing" I use Ilford Galerie Smooth Pearl in 4x6 and 5x7, as they are quite inexpensive in 100 pcs. packs.
