What is the best burner to buy and from where

I want to start burning DVD’s and sell them. Right now I need a stand alone that can burn atleast 3-5 DVD at a time (I want to start off with something small and then upgrade later). I need a burner that can burn atleast 10 a day, three times a week. Also it as to be durable.

If anyone can give any kind of info I will be grateful. Also you can reach me at my e-mail address (Treadstone_T@hotmail.com).
