Bit surprised no one has mentioned American Tourister - the quintessential 60s hard-side suitcases.
I've got a full set of Tiara in gray. Used them on a train tour of the west coast.
Hard-Side Garment bag
Train Case (for the fiancÃ©)
$200 all in. I relined the cases w/ a beige canvas.
Extremely durable, I get comments on them constantly.
