I was previously considering getting a kilt from an independent kiltmaker - but I can get the same kilt for atleast £50 cheaper from Heritage of Scotland as they now have a great sale on! (check it out!)

I'm having trouble choosing the mill/tartan maker. I have the choice of:
Marton Mills 16oz £19.57
N Batley 16oz £14.69
House of Edgar 16oz £29.36

Is there a difference in quality between the mills? and/or which one is "best"?

Im getting the Campbell Ancient tartan
