I have two kilts from www.mcrok.com at this time. The quality is fantastic, their selection is great, and the customer service was fantastic. My second one arrived at my door just 23 days after I placed my order.

I also ordered a kilt from www.irishkilts.net this is the same company as www.scottishkilts.net they also have a great selection, great prices and fantastic customer service.
www.scottishkilts.net now has a machine stitched 8 yard wool kilt available for (I think) $310. Sounds like a great deal.

I highly recommend either company.
