Good to hear from you. Sorry this took so long and hopefully you're still around. As far as my original inkset goes, I bought the Selenium inks for the 3880.
I kind of got lost when all the website changes happened plus I picked up some large format (4x5) film equipment so not much in the way of piezography for a while. I just got interested in alternative processes (Kallitypes in particular) lately though and digital negatives and Pictorico are looking really interesting. I need to sort a bunch of stuff out however so it might take a while.
Send me a message when you get a chance and let me know where you are (I'm in Fort McMurray, Alberta)
