Beware that dye sublimation technology can have the 'fatal' flaw that stored improperly, they images can fade quite fast! Put a dye sub print in a PVC clear 'protector' (which also causes photocopies to stick to the protector) and your prints will fade and discolor. This is based upon having had a close relationship with more than one dye sublimation vendor for healthcare purposes and learning of the limiations/cautions.
Furthermore, dye sub uses a 'color print ribbon' for transfer of the color to dye sub media. The 'ribbon' for one photo is typically 3 sections of color (cyan, yellow, magenta) and black. If you print a photo that is dominantly a single color, the other two color sections are effectively wasted.
Wilt, I fully understand the media issue you mention. There is, obviously, a fixed cost per print.
The one question that I have never gotten a reliable answer to is how one can expect the prints to last in a normal environment. Consider the home, some sunlight, putting the prints behind glass in a frame, etc.
