Fahim-
I'm a little late to this thread but since I was in the market for a tripod and considered the 1550 package I thought I'd weigh in.
I passed on the 1550 w/head and opted for the 1541 with the 1780QR head. About $125 more than the 1550 package, it's not much heavier, rated a bit higher in the supportable weight catagory, and the quick release was a feature I really wanted. I've just ordered the legs and head so can't comment from a review perspective but will do so when they arrive.
I should have ordered sooner- I need the equipment for an upcoming trip and don't think it will arrive before I leave (sigh).
