Same applies to the Enduralast stator, Injun! Actually, that one would be a lot easier to rewind ...
I don't think there's a clear choice between the two systems: as I've said a squillion times, if I was leaving for Siberia the next day I'd probably install the Omega system because it has a longer track record. It's also plug-and-play, and anyone who understands the BMW charging system will find it easy to check out since it works the same way.
As it is, I won't be crossing Siberia any time soon, I do all my own bike work anyway, and I've installed the Enduralast system. It helps that I know a fair bit about electronics, and feel confident installing and troubleshooting this system. I wouldn't recommend it to anyone who is not comfortable soldering connectors, as shoddy installation could lead to rapid failure. However, a properly installed system is, in my opinion, unlikely to fail.
Someone mentioned cooling: yes, cooling airflow is critical to the regulator, and indeed to all semiconductors ... failure rate at 110°C is about 35x failure rate at 55°C. This is the main problem with the stock diode board location inside the front engine cases. I'm amazed the Omega system doesn't relocate the diodes somewhere more sensible.
