I just recently subscribed with the Wuala service. The Wuala service is a dropbox clone that in my opinion is better and has much, much better prices and a very cool Storage Trading feature! Also, Wuala is a LACIE project and I like Lacie, they make good hardware and very good hard drives!

Of course if you use the Storage Trading option in the Wuala service you can have as much Cloud space as you wish for FREE!!! So all the above prices are not relevant!
If you want to join, just click here.
All the Wuala links I have in my post link to my invitation page, so if you join via me, you get more free space to start and I also get some bonus space also. So if you choose to join from this page then thanks
