If you are looking for a do all traction aide $500 is going to limit you on your options. If this is a daily driver/weekend warrior truck I would definitely save for a selectable locker:

ARB = pneumatic
OxLocker = mechanical
Detroit Electrac = electical

All of these are available for the Dana 60 but each is going to run close to $1,000 or more.

I am not familiar with many limited slip units other than the stock Eaton units and the Truetrac. Humbly, I feel the Truetrac is a wonder unit for a do all rig. Its worm gear design doesn't rely on clutchpacks that wear out or need additives in the oil, it's tough, smooth, reliable, and maintenance free. I like it's bias and if the driver can feather the e-brake on obstacles a guy can manipulate the unit to send torque to both tires to help on obstacles that an open diff wont manage through. But it's about $700ish.

As of mid last year the cheapest new option on the market was the Grizzly locker by Yukon Gear. It was ruggedly designed to compete with the Detroit Locker while undercutting its price structure but I've noticed the prices of them have jumped as of late making their price comparable to the Detroits in $550-600 range.

I think a guy would have to take a realistic look at what they want to do with the vehicle and what they are will to accept for potentially negative handling characteristics based on which direction they go.

Hope this helped a little bit Dave.
