I've had many conversations at Q about 299s, 240s, quality differences, etc. When 240s first were discontinued, we had a hand in convincing Q to bring them back. But a year or two later and they've now gone.
I can still get them if I order 1000+ that's enough for the factory to do a small run, and I thought about doing that. But the quality of 299s is now good enough that there is no need. The failure rate of 299s now is close to zero.
