1. Ink jets can be both pigment based or dye based ink. Current Epson dye based prints last long, decades with the right paper. Current Epson pigment based prints can last a century. Longevity isn't a problem.
2. Pigment based prints aren't going to have a problems with running ink.
3. If you are doing black and white, most think that ink jet prints are closer to traditional B&W.
4. The Kodak printer you mention is mainly designed for prints in the studio. It is designed for portrait work flow. You take the shot and give to the client there. I don't know what your exact use was going to be, but thought that might help.
4. An Epson ink jet's color gamut is better then most dye-subs.
5. More material is written and help provided for ink jets.
6. Fine art photographers generally use ink jets. The reasons listed above and by others are the reason why.
7. The dye sub you mentioned costs $1000, but an Epson 1280 is hundreds. I would check the cost per print and life of the printer etc. to compare them.
Bottom line, look carefully before buying a dye sublimation. It isn't that they don't give great prints-- they do. Ink jets are better for most.
