I run OwnCloud on my Synology NAS at home. The Synology has got dynamic DNS and I have then CNAMED the synology.me address with cloud.mydomain.com. The sync client seems OK to me and I can access my files and contacts remotely. Everything goes over SSL with a free StartSSL cert.

I also use dropbox for work stuff that I don't care about from a privacy perspective.

Overall I'm happy with OwnCloud. Sadly they don't have an officially supported OwnCloud package for Synology, but you can have everything I guess.
