I love my 'bad' habit of window-shopping on the AH. I saw a stack, yes 12, of these for sale and decided to lot 200k. Well next thing I knew I had 12 phantom tathlums as 50 WHM.
So I sold 9 of them back at 180k each in singles, coming to a nice 1.6m gil made, only took two days to sell them. I kept the other 3 for myself, my girlfriend and my sister :D.
I also get the feeling that the person i bought the stack off was a gilseller (just a hunch), so double-yay. Lesson of the day: don't be afraid to try what might seem like a ridiculous bid ;) you might get lucky.
