Checkout KK AIR @ 800-262-3322. The only thing they don't have is recessed latches. Everything else about these cases is top notch. If you are concerned with baggage handlers stressing them, go with the extra thick .080 inch wall thickness (aluminum).
SKB offers a cheaper 'plastic' airline approved case that locks as well at about half the cost of the KK AIR case.
There are other aluminum case manufacturer's as well that make good cases. Overall, price points are similar so, shop for features.
The final thought I have is buy the best you can afford because these aluminum cases are apt to last your lifetime and that of your kids as well, a great investment for long term use.
