well, assuming that your more interested in the UK than the US, I got case from PC world, it is a sort of neoprene material (think wetsuit) The problem is that they have one size of case which is exactly the same size as the TR1 but the TR is just and I mean just too thick to fit in. I got the size larger which is labled as B5 size (think paper) but anyway it is far from ideal, it makes the tr so much bigger, however i can keep the power charger and mouse in with it so for traveling it is fine. Anyway the best part is that it was only £10 which is a change for PC world :D
I am however on the look out for a better case which shows off the tr better
