Hagrid's wand?

I hope this hasn't been discussed too often before, but why  does 
Hagrid not be able to buy himself a new wand?
You don't have to be a full -trained wizard to own one ( or the 
students wouldn't have one) and Hagrid's reputation was restored after 
CoS. I'm sure Hagrid kept up his magical education with or without 
Dumbledores help while he was expelled from lessons, so I think he 
could just do at least the OWL -Exams.

What do you think?
