So MarkersNg, many people here share on the options Liaotake your pick.
End of r day , last piece of advise is always try the bag physically before buying it. Remember u r buying a bag to lug your stuff, protect them and more importantly , allow u to retrieve your camera stuff easily. Any bag that fulfills these 3 should be good enough ; another lesson is more pockets doesn't mean better ; they have to be useful.
And if u don't mind pre-loved ; wait patiently on B n S for the billinghams to appear. I recently hooted a almost brand new Hadley pro with shoulder strap (actually mint) for <$300 , not very far off the budget.
Most probably I'll go and take a look next week

Thanks for the help everyone
