Hey, I was wondering what Mods (addons) I should use, there are a lot out, and i was just hoping for some suggestions.

x - perl ftw

Titan panel !

All really depends on what class you are.

There's a few that I use, but not class specific though.

Bongos is my favourite as it allows you to put icons almost anywhere on the screen.
It also has other features like auction house auto add, also when you use the AH, and you open a bag, it will tell you the vendor price for selling and how much it's worth at the AH.
Also comes with map coords and many other features.

If your rolling a warlock "Necrosis" is by far the best tool ever.

Titan bar is an excellent Addon, it's a bar that appears on top and bottom on your screen,
It has all kind of features like a clock, a bagstatus and more.
you can add more features to the panel.
Here you can find the Titan Panel itself: Titan Panel | World of Warcraft @ Curse.com.
And here you can find more expansions for the panel: Search World of Warcraft Downloads | World of Warcraft @ Curse.com.

If you have a Warlock, Necrosis is an excellent choice.
You can download it right here Necrosis 2 | World of Warcraft @ Curse.com

If you have a Shaman, you can take Totemus, It's almost the same as Necrosis for the locks, but then for a Shaman.
Download Totemus here: Totemus | World of Warcraft @ Curse.com.

For all your Addons:
World of Warcraft Addons | World of Warcraft @ Curse.com

These Addons work on the game version 2.1.3, Have fun with them.
