I need to get some shelves on which to store that part of my CD collection[*] which doesn't fit into the tower I bought it last year.

Can anyone recommend (preferably inexpensive) shelves which will do the following:

(a) fix securely to a flimsy wall.
(Yes, it's an outside, and alledgedly load-bearing, wall. Sadly, our house was built by nutters who thought swiss cheese was a valid alternative to brick)

(b) for related reasons, be reasonably light

(c) give good CD-storage for amount-of-wall-covered.
(I'm currently 80 CDs worth of shelf space under the odds...)

[*] Sadly, plans to nail the CDs directly to the wall, glue them to the ceiling, or otherwise cause them to hover above the stereo have all had to be dismissed as unworkable.
