Taco LSD

I need more traction in the rear and don't have the money for a selectable locker such as the ARB or Toyota E-Locker, and don't want the scary or even dangerous conditions that an auto locker such as a detroit can cuase in ice and snow.
Does anyone here have a LSD, or know someone who does? I want to know how well it actually helps, how long it lasts and if your happy with it.
Thanks for everything
