With the exchange rate changing, the Holyrood Modern in Poly/wool blend from Caledonia kilts is down to $127. shipping from the UK is still about 30 pounds, tho. Look up Caledonia Kilts on ebay, they offer a number of tartans, including a MacDuff, which I've not seen in a budget kilt anywhere else.

MacDuff, for you Shakespeare fans, is the Clan name of the guy that killed MacBeth.

Just be sure to order one that's an inch or two larger than your actual measured waistline, as Davey tends to make them small.
