Hard cases - recommendations?

I've got a toploader for my D90 with 70-200 attached, and a slingshot for taking the body, and a couple of lenses & accessories, but think I may require some other form of storage for bits and bobs etc, as at the moment, I've got my flash in it's own case, soft cases for my lenses, USB cables, extra batteries, filters etc all just in a basket.

I was thinking of getting a hard case like a flight case. Does anyone have any recomendations or better ideas?
Current kit:
D90 body
18-105 kit lens
60mm macro lens
70-200 f2.8 lens
SB-900 flash
Some Cokin filters
light tent

then general bits and bobs like hurricane blower, cleaning pens, cables, spyder cube etc, so need somewhere to safely keep all those items. it's for general storage to keep everything together but ideally to also take out and about if needs be to 'jobs'.

Any suggestions appreciated! Thanks
