Luckily, the 128i's have bolted ring gears, which means, with major patience, I could possibly swap the diff myself. That'd supposedly ring out to a mere $850...that's $450 in labor savings! Oh, all the skidding about I could do!
EDIT: I just looked at the process for installing an LSD into your own diff. It looks very technical, but not difficult or laborious for someone with the right tools.

If you have the bolted ring gear you can definitely DIY it, it just takes time and patience. Since you're only doing the ring gear and not the pinion you'll only need to adjust backlash, which sounds scary but is simple as measuring movement and then putting a shim on one side or the other of the diff housing.
We just did exactly this on my buddies WRX, if you come to the go-kart meet he'll be there and I'm sure he'd be happy to talk more about it lol.
