I have the same torch and use a Peli 1500 Case from
Waterproof-Cases.co.uk
It is big enough to hold the torch, charger and a salvo rat jnr.
It comes with a foam kit which is made up of partly cut foam squares so you can make it suit the kit you put in. I went for this so i can be in the back of the van and even if the twins fall on it the case won't even have a mark on it......
If you want i can post pics when i get home
