I don't know about price but I just took off a Skyjacker Track bar that was hitting my front diff and replaced it with a Thuren Track bar. 4 Wheels parts in Hawaii, who installed it, thought it was great. It was the first time they had seen one. I love it.
I had to contact Thuren (www.thurenfabrication.com) and have them send the track-bar to me ($299.00 + $40 shipping to Honolulu - truck location), and then 4Wheel parts installed it. I'm not sure of actual cost of just this as they did other things at the same time. I hope this helps. BTW, I'm on the Kona side.
Everything Thuren makes is bullet proof. They make some of everything you just mentioned. Don doesn't sell the cheapest stuff out there, but you can bet it's some of the beefiest. Click the link in my sig to take a look at his trac bar. You'll like it!
