Help - Buggies - Too much choice

Hi everyone, i am new to this so apologies if this is posted in the wrong place. I am looking for a new buggy for my 5mth old son. It needs to be lightweight, compact, easy to push and get on the bus (can't drive) and not collapse when i put shopping on the handle. Oh and it needs to be tall enough for my 6ft 2in hubby to occasionally push. . . what a list, sorry - Can anybody help?

My friend has a McLaren stroller which is nice and tall for the height and quite sturdy but I've no idea of the model I'm afraid.
