I've also had good service out of Blackburn racks. I have an Expedition rack that I used for touring on my around town bike. It hauls much heavier loads home from the store than it ever did on a tour.
I also still have the first rack I ever bought back in the early 70's, a Blackburn. It is still doing its job on my daughter's commuting bike.
This Blackburn rack is probably 40-years old. The one-point brake bridge attachment point is surprisingly sturdy.
