Digital BW, The Print

I just discovered that inkjetart at www.inkjetart.com is offering test 
prints of epson 4800 output using the PK black on a variety of "glossy" 
media for about $15 including priority mail shipping in the US. (Its 
their test print not one you send them.) They don't print BW with all 
of the various toning possibilities but they do provide examples of 
neutral BW output. I ordered mine and am eagerly looking forward to 
evaluating the prints.
