The very first kilt I bought was a homespun economy from the Celtic Croft. It's worked great for me, although I don't really wear it anymore, since I lost a little weight and HAVE to wear a belt with it (otherwise everyone would know what I wear under it!). I can't compare it with a tank because I don't have one yet.

There is a link to the sporrans once you click on the accessories link at the side.
