what Burner & Cdr's?

I have a HP 2x2x6, so I believe its time I upgrade to a new burner. I was wanting to know what everyone else's suggestion would be. Also I'm using Memorex CD-R 700/80min cd's, and sometimes my Dreamcast wont recognize the discs. I was looking to ####t using some other type of CD-R. What kind is best for burning backups?
