I understand that a decent local used 2LT should be 30-50k depending on the model and condition. "Kabuli" ones were still going for 75-80k the last time I checked.....
Best place to get a good one would probably be Quetta etc. where these are normally taken off NCP Surfs/Hiluxes. Availability of 2LTs in Rawalpindi & even Peshawar, has become quite scarce but you can find something good if you are lucky.....
3L would probably be a bit more expensive owing to use in loading Hiluxes....
