Well this going to greatly depend on how much you really want to invest into an attempt at fixing your wander....as it may very well NOT be the trackbar...
You got lots of options in your price range but you may want to think about a conversion bracket to run the 03' and up bars...lots more options then.
If you want to get buy with a good bar for now so you can throw money at more important things a good bar and great price is the Moog bar. substantially thicker and stronger where it counts. Here is a comparison between the stocker and the moog.
Solid Steel Industries TB Bracket and Bar...No troublesome ball joints, no loud Heim joints...
I also like the look of SSI's DSS Kit, The DSS, also known as the "Darins' Steering Stabilizer" is designed to eliminate steering wander in the Dodge Ram pickups. It does this by adding an additional bearing to the bottom of the steering box sector shaft and by adding an additional cross member tying the frame rails together eliminating frame flex. In other words, takes the slop out of your steering.
Here are some shots of both-
additional info for SSI's products...it seems the the bracket costs about $185 the bar is another $315 so $500 and its only good for up to 3" lift
Thuren Fabrications 2nd gen bar is good for 5" - 10" of lift...the site says they are currently out of stock....seems to go for around $360 according to a gentleman on another forum so dont quote me.
Somehow this drop bracket seems inferior even to the bolt on one i currently have on(provided it was welded at the cross member also)...im sure it isn't but it just seems like even with the one weld on brace it may not distribute load well...but then i'm not an engineer by trade and also one could fab up additional gussets to tack up with ease so not that big a deal..
I actually like the skyjacker bracket and bar...youll notice the bracket is superior in design to most other out there. price ranges from about $260 to $350
To touch again on that steering box brace...its thought by many the darrins brace can put stresses on the sector shaft with frame twist while offroading...this one does not...and i like it a lot...also seems easy enough to fab and guys with tractor parts stores near them can get all the parts to make it there.
This is all coming from research i did for myself but i was only interested in bars good for 5" or more of lift which is why all the brackets.
I went with the moog for now so i could throw money at gears and recently a Mega Viper Trans. Below is a shot of mine installed...you know i had to paint her up.
