The SHF is a great knife and one that'd tempted me for a long time. I find some of the engraved models greatly appealing and others not so much, but the quality of the work involved for all of them is exceptionally good. I'd admired the coloration and detail on the Plague Doctor and like seeing pics of those owned by

,
Kmikaz3
, and others, but that particular design isn't something that I really felt I'd want to own and carry. I fell in love with a Northwest Coast Edition I found online last fall and pulled the trigger rather quickly when I saw it was S45VN. I'm really glad I did as it's an exceptional piece and the notion that the SHF melds the primary attributes of CRKs and RHKs is both interesting and appropriate.
Almost immediately after getting my engraved model--which gets used in an EDC role--I did what Chuck and
BTTLBRN
suggested above and started looking for a Plain Jane SHF on the Exchange to carry as a work user and was lucky find one at a great price. That one's an older S35VN model and is nicely broken in, has a great re-profiled edge, and is super smooth with great lock-up and release. Here's a couple pics of my two...
...and on the subject of Knifecenter, I would mention that I've never pre-ordered from them (or anyone else for that matter) but have purchased numerous knives there over the years and have always found their responsiveness, quick shipping, and pricing to be excellent. I've also been able to take advantage of their rewards points for both discounts on knives and full value for things like beads and CRK slips.
OP, if a Plague Doctor is what you really want I'd keep scouring for both used and new on all markets and not just wait on a pre-order. Good luck on your quest!
