If you are using Epson papers on this printer there is really no point in doing your own profiles as the Epson profiles are excellent. Depending on how many papers you plan on using it might be more economical to have profiles made for you rather than making the investment in new hardware & soft ware. In terms of cost effectiveness, ArgyllCMS is as good as any other software out there and it's free (though there is a moderate learning curve and familiarity with command-line computer usage required). The software supports almost all hardware out there (I use it with an i1 Pro spectro). My own personal bias is that unless one is interested in color science (which I am), do it yourself profiling is an unnecessary cost and use of time.
