I by no means mean to downplay any of the extraordinary full UI's so many talented people have created, but for simplicity and maximum viewing area on the screen i've never found any single UI that works as well as just putting together your own UI from individual peices. It's not very hard to do peicemeal and can be pretty fun looking through the various options too.
Once you get the basics done it's just a matter of updating peices now and then as incompatibilities arise with patches or something new and nifty comes out. Ya may want to give it a try.
