Hello, hello... I want to buy DVD RW for my R51, but original from IBM is too expensive. Will NEC ND-6500A (http://www.nec.co.uk/ND6500.aspx) or NEC-6650A (http://www.nec.co.uk/ND6650.aspx) work with my R51 without any additional parts? What do you think about NEC DVD writers? Mayby have to choose other manufacturer and writer? What are yours proposals? Regards, Michal
