After some fiddling around with various addons, I decided to stick with the Blizz-UF and spice them up a litte using the following:
-
FocusFrame - to add a, well, focus frame
-
Simple Unit Frames - for various little tweaks to the blizz frames
-
Status Quo - different bar textures
-
Visor2 - to move my frames to center bottom of my screen
It currently looks like this (with focus set):
