1) I rode a Solid for a year and half without any problems. I can't even imagine breaking it, either; it's heat-treated 4140 chromoly.
2) I've had an integrated headset for about eight months now, and I haven't had any problems with it, either.
3) I had a Pig for over half-a-decade without any problems.
4) The only headset I've ever actually broken was the King, which cost more than double the cost of the Solid, and three times the cost of my Pig and FSA Impact, and it only lasted for a month or two.
