having said that - i have flown thru the LCCT at KUL - and while it certainly was primitive it was not dreadful.
BUT at the same time I was getting a great price for a J seat.
My next trip I am paying $315 to fly KUL to SYD in J on D7 - and certainly will not be complaining about having to walk a ways at KLIA2
