What is best flight booking engine to use for side trips in Europe?

[pmk]

I want to book some additional side trips (flights) in Scandinavia to supplement my Rtw ticket. Under google search it seems like a zillion flight search engines come up. Can anyone recommend a good one to use. I will be paying with an Australian credit card. Ideally I would like to book a multi-city trip but suspect I will need to book 4 single flights which will not be connected. There will a few days between each flight so connections not an issue. Thanks in anticipation

Skyscanner.com, it will scan all the local websites and point you to the website with the best prices.
