Some kind of JCB phone? Or a smart phone with a ridiculously heavy duty case?
the jcb one gets mixed reviews but would be my choice
Jcb one is what my grandad has and it's a beaut. He just can't understand how to put spaces

Makes me crack up when he texts me haha
Samsung Galaxy XCover 2. £135. Doing some development work on them at work. Seem fast and are waterproof and rugged etc!
I had a 3gs for ages with an otterbox case. 2 years used in heavy workshop environment absolutely fine. Best case ever. My father in law now has an otterbox case his iPhone 5s. They do them for a variety of phones and cheapest on amazon. Have a look at some Youtube reviews.
