in 50 to 60k range you can get following
Samsung note 2 (55k)
Samsung S4 (72k) price will go down after some weeks
Sony Xperia Z (58k) price will go down after some weeks
Sony Xperia ZL (64k) price will go down after some weeks
HTC One (86k current price is too much)
iphone 5 (70k)
and there are rumors of cheaper iphone too
HSN is now providing 1 year local warranty on iphone 5 and as per my knowledge no one in pakistan provide local warranty on iphones.
I personally think right now it is not the wise time to spend such huge amount. more phones are coming soon and bit late like Samsung note 3, Xiaomi MI-3 (beast), Sony Xperia ZR, iphone 5s/6, Google Nexus 5 e.g.
First make sure which features you want in the phone, phone size, value for your money, read reviews & users comments on gsmarena watch video reviews on youtube e.g.
If you are ok with Samsung note 2, 3 and S4 sizes then I would say wait for note 3 few more months if you can't wait then Note 2 is there.
In case you are not comfortable with note series size then you can grab any one of the above phone or wait little for some upcoming phones.
Atleast get a 2gb ram phone (future secure in apps & games)
Rest its up to you.
