I wouldn't give you tuppence..
I went into a camera shop today (this is not a joke, or may be it is) and asked to look at an 'ex rental' panoramic camera as I have been after a certain model for a while now. I told the guy who handed me the piece of metal;
"This camera looks like its been dropped multiple times, thrown in the air multiple times, placed under a bus multiple times, dropped down a drain, taken out and then kept in a box of sand. It may also have been farted on due to its musty smell..."
"That may be sir, but its in fully working order, and the lens is great, except its a bit scratched.."
Ex rental my arse!
