I, for one, am VERY happy with my heavyweight SWK. It's one of my go-to kilts for when I'm out and casual. It's right around the same price range at $130.

I don't know anything about ALTKilt, they might be awesome, just letting you know that I really like my HW SWK. I got the black "shadow" tartan, and it looks awesome.

Happy hunting, and post pics!
