As someone who just bought their first kilt, here's my take on it. Oh yeah - I probably bought it from the Scottish shop Colin referenced in the first post.

Yes, their prices are much higher than anything else I've seen. Fortunately for them, I was in a hurry and needed this kilt for my wedding. But I've received some things that give me the value for what I paid. The staff was incredibly knowledgeable and walked this rookie through every item and procedure of his first kilt. Secondly, my kilt has a lifetime warranty. For the rest of my life, cleanings and alterations of any kind are free. Not bad. And I can drop it off instead of mailing it to a far away place.

If you value customer service, a great atmosphere and top-quality products, I absolutely recommend this particular store. That is (or at least should be) the value of a "mom an' pop" store. But if your main concern is price, eBay away! I don't know if I'll get my next kilt from the store, but I'm at least considering it for the service alone.
