The kilt I just bought "new but used" off Ebay appears to be a Kiltmart kilt. The seller didn't say who made it. I checked the Kiltmart site and the one I just got sure looks like one of theirs. I also have a Stillwater kilt and it's definitely not one of those.

The quality (for a budget kilt) seems pretty decent. It hangs fairly well, has decent swing, and is a nice material. The front apron, like a SW kilt, is a bit narrow for my liking, but it's certainly an acceptable kilt. There's a pic of it in my "new kilt" thread in the show your pics section.
