debuff timer addon please (e.g Rend)

[vexen]

I have an addon that counts how long rend has been on my target but what i want is a timer that counts down

DoTimer - Shows the debuff icon with a numeric countdown next to it that displays in seconds.

Chronometer - Similar to DoTimer with an icon and countdown timer except it shows a cast bar that gradually depletes as the debuff counts down.

I used DoTimer at first but I found it rather clunky and visually unappealing, not to mention it doesn't track all debuffs (It never showed any warrior debuffs for me). I now use Chronometer; much better in my opinion. I'm visually oriented and prefer cast bars as opposed to simple countdown timers. I haven't found a debuff yet it won't show.
