A google search for Dye Transfer reveals the dye transfer workers and the DT SIG on Yahoo. It is quite active.
Ctein and Jim Browning are both DT printers. Ctein works from color negatives and makes prints using Pan Matrix Film, whereas Jim works from Matrix film via Transparencies. Both of them produce stunning prints. If you have not seen one, by all means make an effort.
Ctein and Jim both accept donations of DT materials. My last box of 16x20 Kodak DT paper went to Ctein. He is a very nice person to communicate with and does superb work.
