My mom just got one and it was nice to setup, but I read somewhere recently that people were discovering the hard way that the standard ink fades very easily. I think you can find archival inks though.

I have never heard of Wilhelm Research, but this pdf has a comparison of fade times, and the EcoTank is listed around ~2 years under glass, at least dark storage rating is >100 years for all of them
