Lego minifigure display case availability?

This is a general question but does anyone know if the company making the very excellent minifigure display cases, the nice 16 figure plastic ones with the Perspex fronts, as seen here on the JL website - http://www.johnlewis.com/lego-minifigure-display-case-assorted/p23166348, are still making them?

I guess the obvious follow up question is, does anyone have a reasonable line on any of these?

Thanks
Matt
