I had some email discussions with the folks at Wavetrac a month or so ago. They offer a drop-in pumpkin for the MT RWD 228i for $700 and for the RWD M235i for $600 (see
http://www.wavetrac.net/application.htm). Both of these apparently have bolted ring gears.
For the xDrive M235, they have one that's appropriate (list $1300), but as the xDrive models use a welded ring gear, the existing unit needs to be sent to them for removal of the OEM gear and welding it onto a mount for their unit (with an additional $600 shop charge). That moved my doing the LSD from the "this summer while I'm out of town on vacation" list onto the "maybe" list, mostly due to the turnaround time sending the differential to them.
There's a bunch of BMW folks using Wavetrac LSDs. CalWaterBoy in the E90 forum over at the other guys has had one in his 335i convertible for at least 4 or 5 years with no problems and swears by it.
