You can get the "Casual Kilt on Sale" from Burnetts and Struth http://www.burnetts-struth.com/casual-kilt-on-sale/ for $199 and that's in wool. They have Cameron of Erracht Ancient and Modern listed as being available right now. Again, not quite $150, but honestly a GREAT kilt for the money. Having just received one in Galbraith ancient I'm a suitably impressed with the quality of the kilt for the money and am pondering ordering another in a different tartan.

Another choice to consider...
