I got mine from Kilts Wi Hae: http://www.kiltswihae.co.uk/kilt-mak...lies-354-c.asp I got mine via their eBay store, but they're the same ones they have on their site. The only issue you may have is that they tend to take a while to arrive.

I've used the buckles with and without the leather tabs, and while the leather tabs do save you the trouble of making them, the fabric tabs are a lot easier to sew on. I wound up marking the holes on the leather with a pin and then using the denim needle on my sewing machine to manually punch them, so that I could then sew the tabs on with a regular needle with relative ease. Yeah, I'm not the type to buy a tool that I'll only get limited use if I can improvise with something I already have. But when it came to the fabric tabs, I used Barb T's flash-making technique to create them: http://www.xmarksthescot.com/forum/f...flashes-32660/ Just be sure to leave a gap in the hem tape for the prong of the buckle to poke through.
