Walter,
In a Salon, they need to be pretty nice,so William or Wendy's suggestion might work. If you're handy, build your own "browse bins" out of good plywood,with a veneer or some MDF, if you have the time and the talent. But I like to have sided on mine,especially
Low end, I would go visit either online or in person, something like the 'Containerstore" and see what they have that you can convert and use. Even something plastic and clear, can be sprayed a nice matte black and work.
