asp.net mvc models vs entity framework models

Would it be best practice to create a model in your asp.net mvc - model folder. Use these models with your views and by using a service layer to "adapt" my model to the EF-model.

Or have you used another approach. The problem with this approachs is that most of the times my (selfmade)model is a copy of the EF-model (not dry)

So can someone explain me what models to use with your view cause it is becomming very confusing. model / viewmodel / Entityframeworkmodel ....

Solution :

Thanks for answers all guess i am at the moment to refactor some things!
