adjustable trac bars?

[beakie]

After lifting my Jeep 3" I am in need of a trac bar, and am looking at a few choices. I have done most of my business for parts through Rusty's Offroad and had wanted to stick with him. From talking with people and reading on here I should go with an adjustable, and a heavy duty one in case of future lift. So my question is what are people in here running, or maybe not running for some reason?
Rusty's: This package includes our TB-200 Heavy Duty Trac-Bar and Frame mount as well as our Frame Stiffener which mounts from the passenger side unibody to the trac-bar frame mount.

to me this looks rather good, and the price isn't bad at $220, but any and all thoughts are appreciated.

A trackbar is an important investment,get a real one and dont look back!

Go Rubicon Express. For $250 you get the track-bar and bracket. I run it and wouldn't trade it for anything. It's almost too strong....

sorry for the newb question but what does a trac bar help do except to center the axle??

Either way here's a pic Rusty's displays, its enough to impress this newbie (which of course doesn't take much)

With the one I mentioned I also get the frame stiff'ner all for less than the RE one without the frame stiff'ner. I am not worried about the money, if popular consencus is that Rusty's aren't worth it I would shy away, I want to get my money's worth and from what I see this setup gives more for less.
