best roof racks for 2010 model

[skyva]

Hi, I have used up a lot of the room in the back of the car with kids car seats so I can no longer put long items in the back. What are good roof racks for a 2010 outback? Ideally they should be easy to remove as I would prefer to only have them on when I need to pick stuff up from Bunnings etc.

What do people pay? Should I go for Subaru originals or rola/other?

Thanks.
