they will probably have some sort of a deal at LB, but not sure how much. They also offer a trade in program, but again, I can't remember the details.
Reach out to Sal at
salpassanisi@xrite.com (he works for Pantone) and ask about the pricing and what he might have available. We recently bought a new ColorMunki (ours is getting old and I had to patch it up couple of times), Pantone was running a great promo at the local show.
You are looking for a coated formula guide. Usually they come in a set, but you need the coated only. I would also suggest getting a Bridge as it gives you the aproximations for the Pantone numbers when done with CMYK. This should help with your Kornit so you know how close you can get on some of the colors. . .
You can have them shipped here and I can either bring with me or mail to you.
