I too am a MacKenzie. My grandmother was born a MacKenzie. Right now I own a cheap basic MacKenzie kilt that i got for about 40 bucks, but I too intend on buying the Weathered MacKenzie here soon. I think it looks nice.

As for the original question, I do think that the MacKenzie has kind of become a universal tartan, but like any tartan, i think you should buy what you like, and just treat whatever you decide to buy with respect.
