I use (and pay for) Spideroak pretty much for that reason but given that their client is not open source I kinda feel like it's just homeopathic security. They could backdoor my client and I wouldn't know better.
So I definitely wouldn't store very sensitive stuff on SpiderOak either but I guess it's slightly better than dropbox.
