hi youzee,
my advice would be to go for this set with your eyes close. don't pay this much for chines set if you can have the original 1,
you can get a good set with original charger and data cable in 17-18k max (17000, 18000) and if you have little less budget then go for older version of this which is (lg optimus lte) it is for 13-14k max,
things to check..,
it should have eng jelly been rom.
no koren app and no sms prob. (check by sending loooooooong sms to ur phone)
always check signals (should have proper signals , compare it with some other set with same connection)
check screen properly it should not have any major scratch
check screen for any dead pixel ( do this by going to wallpapers or gallary and view different pics and look for any pixels which are giving red/blue or green colour on white or black background.
on last open back cover and check if the set is open for any repairs or not. (don't buy if the set id repaired)
goodluck buddy and plz share with us when u got one. advance welcome to LG Club.
