I would suggest LiteON anyday. They are the best in terms of reliability, be it CD-RW, Combo or DVD RW i always suggest my friends LiteON. 2nd Preference will be for SONY [Box Packed]. I along with my 2 other frinds are using for the past 1.5 yrs and no problems so far. ASUS is too expensive, Samsung and LG are doubtful in terms of reliability in Long Run. Don't buy any drives which comes loose. Always prefer which comes Box Packed
