I don't really understand your question?
You want an existing "user model" that is written without Active Records?
It all depends on what you want in your user model. There is heaps of CRUD examples and stuff out there, but you'll have to tweak it all to get it to work with your table names, column names, controllers that call your model etc.
Time to get your coding gloves on and do some coding!
