Looking for advice for a Benq dw1620

From what I see here, the Benq dw1620 comes highly recommended. I’m in interested in purchasing a DVD recorder, where is the best place to purchase this Benq? I live in the Houston area, is there a store with the best prices or somewhere on the net?

Also, I would be trying to install this myself on Win XP home.
I currently have CD burner with Nero express.
Does this DVD burner come with any software.
Just want to get help on how to install this software.
I’m new at this.

Thanks, Danny
