I just got the Sony drx500ul. Firewire and UB 2.0. A little expensive at around $400.00 but you can find it online for less. It has burned every disc i put into it without a coaster yet. Used Verbatim, Sony, Fuji, TDK and Memorex. It also handles all the formats and so does my standalone so I get whatever dvd-r is cheapest or on sale.
