UI?

[Shadowspirit]

I was just curious to find out what UI people are using. I personally have never really used that many addons until I started raiding last year in kara and have always used the default interface. Now, I have so many addons that I can hardly see anything that is actually going on during a raid. So my question is, does anyone know any good space saving UI? I have been testing out spartan, but you have to download alot of other addons to do basic things like timers on buffs.
