N8N, I would do this with you, but I don't know how low would the seller go. Also, I don't think this keyboard gives you double shots for all the keys. Looks like there are a bunch of keycaps with a transparent cap on top for relegendability.
As for dye sub keycaps, I think Realforce are the more readily available, new, keyboards that you can buy today with dye sub keys. dye subs are indeed very nice. I think the last dye sub cherry keyboard went for over $400.
