How much time do you spend designing your characters?

A comment (which hasn't been cleared yet, or I'd link to it[link]) on Damien's post about naming conventions in WoW got me thinking about how much time everyone spends designing their characters.

I tend to hit randomize until I see something in the ballpark of what I'm looking for and then tweak the individual features from there until I have something I like. How many of you spend a lot of time customizing the looks of your characters? How many of you just hit randomize and jump on in and start killing things? Let us know.
