Clone records's entity and all related entities

Hi everybody,

I need to create a clone button for a customer to allow duplication of record inside CRM2013. The duplicate, for example of an opportunity, should include all the related entity of the original opportunity ( account, owner ....). I've seen that this is a popular topic on the web and i would receive an advice if buy a plug-in or develop code.

I would prefer to develop my own code but i wasn't able to find a detailed procedure. Did anybody have any solution?

Best Regards
