I don't have any experience with the the company mentioned, but I do remember Scottish kilts having a sale on some tartans, and MacKenzie modern being one of those tartans.

I have had great dealings with them in the past, and for $291 for an 8 yard worsted wool machine sewn kilt, or $351 for a handsewn, that's pretty darn good. You would have to email or call them to let them know that you wanted it to the stripe.
