what burner should i buy , also is there a differnce between 16x and 20 x as far as perfromance

hi ,

i was just wondering , around here the closet store being wal-mart they have 4 drives to choose from which are -

lite on 20a1p 20x
hp 1040 i 20 x with lightscribe
sony dru 840 a 20x
sony dru 830 a 18 x

which of these do you guys recommend , also i had a 16x lite on , is there any difference the quality of the burn with the 16 or 20x or would the burn quality be about the same . thanks fro any help

 

Lite-On would be the best choice although the Sony drives are rebadged Lite-Ons

and NO there will be no quality difference in burns between the 16x burners compared to the 20x burners
