Utility Kilts (i.e. 'Modern Kilts') that are made in American and Canada and I can highly recommend... in Alphabetical order to be fair:

www.Altkilt.com
www.Amerikilt.com
www.Freedomkilts.com (THE OWNER, Steve, ALSO OWNS THIS FORUM)
www.Rkilts.com
www.utilikilts.com (which you already know about)

Beware of things / prices that look 'too good to be true'. They usually are.

The ones that "UT Kilts" sells are made in Pakistan. "Got Kilt" sells kilts from Utilikilts (they wholesale for them) as well as ones made in Pakistan.
