All Plaid Out

Currently seeking out a plaid scarf as a gift for my sister-in-law...now realizing that a good plaid scarf is not so easy to find.  Sure there is the classic Burberry, but I don't think that is quite what she desires.  (Not to mention that the $350 exceeds our secret santa gift exchange budget.) How in the world is this so difficult?!  Would love any suggestions...

PS. I would actually be quite delighted to receive the aforementioned luxury neck warmer. If anyone out there is listening.
