Where to buy cheap used or broken phone or 100% accurate dummy phones?

Hi I'm thinking of trying to design a case for a phone or maybe some stickers, just wondering where I can get cheap used/broken phones, or maybe dummy phones that are 100% shape and measurement like a real phone? Thanks

ebay would be the obvious choice.....

might also help if we knew whereabouts on the planet you are.

I live in USA. Just wondering if those dummy phones could actually work and if you design a sticker or case using it, will it later fit on a real phone?
