Slot-Loading(?) Messenger Bag

So....after looking at the specs of the Sony Vaio Z2, it looks like I'll be needing a new bag.

something like this: Booq Cobra Lift - I would take it, but its too rich for my blood, my budget is not much higher than $150 before shipping

some specific features I'm looking for:
*NON-flashy exterior - refer to booq products for reference
*exterior laptop compartment
*zippered main compartment that can hold a bible-sized text book - not too anal about size though(perferably with no small pockets inside - wide ones meant to hold magazines would be good though)
*handles + shoulder strap (with non-wimpy(or is it MORE wimpy?) shoulder padding - refer to link for non-wimpy reference)
*NOT leather

as for size, something that was MADE for a 14" laptop would be nice. The Z2 is 13" wide, but I personally prefer a little wiggle room.

any recommendations? NOTE: I am in Canada

 

Have you looked on ebags? They have a tremendous selection.
