how much is he asking for it? and how many miles are on the car?
and it will cost between 500-1000 to get it repaired....if you decide to fix it before you break it then you can just have your stock one welded, which is cheaper than buying a replacement one (500), then have a transmission shop install it for probably about 500...if you break it first a new lsd will cost you 500 then welding costs and installation costs
basically: fix it first, 500....fix it after it breaks, 1000
