What you "heard" about decreasing MB quality, is what I've heard since the late sixties with every new major model release. People ALWAYS say "they're not built as well as the last model."
They're indeed always built differently than the last model. Otherwise, why bring out a new model. Things change, and for every apparent change for the worse, there are two improvements for the better.
I'm glad everyone is okay after the accident.
Have a great day,
