I'm also looking for some unit frames, been using standard with CT Mod since the release of WoW now, but I finally need something more than that for arenas.

I've tried AG-UF, but I miss the "countdown" on buffs that I have casts that I see when I target someone.
I've also tried X Perl, and I really like all the options, but I absolutely their layout, I want something that looks more like AG (name in the healthbar etc.). Is it possible to change the layout? Because they would be perfect if not for the layout.
The I've tried PitBull, but all the settings are just too much, I want something that's a little easier to configure as I don't need al those options and then have it bug out on me (bugs when you change buff/debuff sizes or change locations of target's buffs/debuffs).
Is there anything else I should try if there's no way to cahge the X Perl layout?
