So it's about £70 now with the battery pack, it's gone up a bit since I bought one and I remember it feeling a bit galling at the time having to get the battery separately (tho I suppose it makes it cheaper for someone who will use the mains at all times). That feeling went after a time, I've had the radio years, the battery still works perfectly, it's still decent value.
Didht know about a case, but is available for £15: http://www.ogormans.co.uk/acatalog/pure-one-mini-case-vl-61384.html
