SOLDIERX.COM Nobody Can Stop Information Insemination

I am a new member and found SoliderX though Defcon 22 videos. I figured who else would be better to answer this question than you guys.

I am looking to store some personal files on a Dropbox-like system and knowing Dropbox isn't secure I found Spider Oak. Any Opinions? I don't know want to set up my own ftp server for this purpose and I want drag and drop features of spider oak / Dropbox.
