Digital BW, The Print

What are some digital photography venders that are similar to Ink Jet 
Art (www.inkjetart.com)?  Ink Jet Art offers some useful technical 
discussions and a newsletter that I like to read.  Aren't there some 
similar operations?

In fact, I feel sure I saw a post on some newsgroup, not long ago, 
that listed three or so such businesses, including I.J.A., but I sure 
cannot find that list now!  (My immediate interest:  I.J.A. said 
they'd be reviewing the EPSON 4870 scanner shortly; I am looking for 
other critical reviews.)
