thanks for your replies and your suggestions!
The burner has worked flawlessly for at least a year now both burning and playing audio discs but like many other traders, I really give this thing a work out!

It still burns discs right now so I'll keep it until a new one is in the budget.
As for DVD burners, I don't burn movies and I seldom watch music videos but it might be a good idea to get for the larger storage.
