Eaton Tru-Trac differential opinions?

I've heard nothing but good things (Eaton). When I was having the rear end rebuild in my Dodge 4x4 1500 I considered one of those but the price wasn't worth the application it would be in... which would be mostly street driven and only 20% used for 4 wheel drive with zero drag racing/slick usage...its a truck. So I just bought a brand new Auburn for 400 . It works great and makes no noise. All of the Auburn's I've ever bought have been used and I've only lasted five six years tops but that's used. So this is my personal experience with the new one and we'll see how it goes. Ultimately I'd say if you have the extra coin get the eaten but I've never had any problems with a regular clutch type Sure Grip like the one I have in my 67 Valiant except for when somebody sets it up to tight and it's full lock 24/7
