Welcome! I'll put my vote in for Stillwater, but I'd really recommend USA Kilts because for just a little more money, you can have it made to measure--custom fit! I have one SWK [Wallace Economy] and like it very much excpet for the 24" length which on me makes for a very traditional rise [I'm 5'11"].

For more choices in tartan, definitely check out USA Kilts.
