I know I can convert an HP 430 to a 450C by purchasing the Color Upgrade Kit, for a few hundred $. My question is, what does this kit consist of? Is it just ink cartridges? Does it even include the ink cartridges? Is there something else - tubes? Frame? Firmware? Is the result really completely equivalent to a 450C? HP says there is no upgrade from 430 or 450C to 455CA, because "it is unlikely that an engineer will become a graphic artist. . ." I thought the 455CA was the same as the 450C with macintosh support and postscript. Am I wrong? Is there a difference in print quality? Thanks in advance Greg Faris
