I have some HKP, but I can see how people would stray from them. I try to order just one from every sale (except for blanks; can't have too many dank blanks), but that's the thing: there are so many sales, after a while they become too commonplace. For me, part of the artisan appeal is how rare they are because of the limited production and sales, and the HKP sales are made every month or two with seemingly no limit.
That said, I do appreciate Martin's effort into having an artisan on everyone's board or hand. Heck, I have a red GasMask on my Realforce at work and the office manager noticed it, craned her neck to get a better look, and exclaimed, "That's really cool!"
