Considering the level of engineering and the ease at which everything installs it's a steal. With a donor axle prepped, you could have the entire system installed, including the removal of the stock components, and driving it in a day. No driveshaft modifications (running the stock Sidekick front), only requires a flange swap at the pinion on the donor axle. With the cost of Toyota axles, custom driveshafts, slip-yokes, etc.; this is the most straight-forward system. Food for thought...
