I'd suggest Owncloud for that, on a server running in your own home. Encrypted file system (LUKS), the works.

Pretty much identical to Dropbox and just as stable, IMHO.

Pricewise? You can buy an HP Microserver for about $300 that's capable of 12TB of storage on the top end (more if you get fancy with external arrays), whack it into a APC UPS for another $50, and just run it off your home internet connection. Hang a free domain hame at afraid.org off of it, and run a script on the box to keep the hostname pointed at your dynamic IP if your ISP won't give you a static one on reasonable terms.
