There are some nice styles so far. However, there are no exceptionally brilliant styles yet, Let's be honest there's not. I think they will come though in time though but these will be commercially based not free.
The styles you will see will wipe the floor with the current styles already submitted.
I'm not putting too much effort into skinning until the final version. My XFStop was just to get familiar with the style system, and yes there's more than just simple color changes I did to mine. Actually put quite a bit of custom code in surprisingly, but none-the-less hang tight until 1.0 comes!
