The main UI I use. Made some tweaks to it after having seen Eoy's(Forte @ Kazzak-EU) UI. Mine was similar, but I liked certain aspects of his better.
(Actually took that shot for the chatlog after having realized what I had caught. They were hiding near the AH, so everything after I left made its way into General a little later.)
Got bored and tried my hand at something relatively minimalistic versus what I typically use. I'll probably revisit this for my warrior at some point.
I usually like information easily at hand, but lately I find myself removing things that I don't use faithfully.
