I have for sale a Crumpler Karachi Outpost rucksac. It is camera and laptop bag but can be used for other stuff.
All the divders are removable and can be used in differnet configurations as they are velcro.
Its in good condtion apart from a seom small marks on on of the divders.
For a full indepth review of it see here
It was about £160 new I bought it Australia so was in $AUD and am looking for £50 inculding P&P.
Would also consider a trade for an underquilt as thats that am hopfully going to buy when it sells.
