Shock racks are great for that almost complete piece of mind. While I've never had a major accident, my rack has gotten it's share of being bumped and shoved around. Mike actually dropped his off a loading dock, and it did nothing to the gear inside.
I cannot speak to the SKB, since I have no experience with it. I do have experience with SKB in general, though, and I think their stuff blows. TKL is a much better company. Personally, I have a Mesa, but it is no longer in production.
You can see that everything gear it mounted to is mounted to a suspension system. The eight holes in the bottom of the rack are where I removed the rear shock supports for the back of a power amp. If you can find one of these used, grab it.
