to tell u truth
ALL DVD DRIVES ARE EQUALLY PATHETIC OR EQUALLY GOOD
most drives that come in india are oem drives(which are not known for their quality according to cd freaks, they are made to last out warranty time of system builder).
also the brand and manufacturer are different.thus u can rarely trust a brand name here.
eg.
sony drives are sometimes liteon and sometimes nec.
well all dvd drives available in india ->sony/samsung/liteon/lg have shown tendencies to crap out after about 1.5 years of regular usage.if u rarely use the drives , it may last a little more.
surprisingly enough they last good for their warranty times(1 year) and after that like a time bomb they go kaput!!
the performance varies a bit but cannot play decider as diff is only bout +-5%.
that is why we don't have any clear winner in dvd burners category.
moral->
1. know what u want sata/pata
2. lightscribe is a no issue due to rare/expensive media
3. performance diff are non decider(media is only till 16x). thus 18X or 20X may not be most intelligent decision
4. buy cheapest drive available in the nmarket . it will last u good for a year(within a year u can always RMA it)
meanwhile save a little per month for a year to buy ur next drive.
