Seems like a great place to jump in.

So far I have:
1- USAK casual in MacMillan Black PV
1- Currently being made in Lochcarron Strome MacMillan Old Weathered
1- Kilt length of Lochcarron Auld Scotland tartan being shipped (thanks to Josh for the Ebay heads up!).

Still on the short list:

1. Strathmore's Lochaber WOB
2. House of Edgar's 13 oz.MacMillan Hunting Modern
3.MacDonald Modern (?) I love the NS Highlanders 2nd bat. kilts (Paternal grandmother was a Scottish Kellie, sept of MacDonald as far as I can find)
4. Marton Mills Holyrood
5. Lochcarron Isle of Skye (really common, but damn is it pretty)

Just thinking what fortunate times we live in to even dare to dream of having more than one kilt! Blessed indeed
