Couldn't find exactly what James referred to at CPC (maybe I didn't look hard-enough), but
there's this: Maplin Case
at Maplin. They do them on half-price deals fairly
regularly - I have about 8 I think!
However CPC have a large range of
foam-fitted cases; Just do a search on "Case; Foam" on their website. Various sizes and
prices - some (plastic) much cheaper than Maplin.
