Get a SugarSync free account, then divide your stuff between the two. Dropbox and Sugarsync play nicely together; I have both running. SS is cheaper for when your needs run into the tens of GBs, as mine have. It also lets you mark folders for syncing, without requiring you to move them.
If you use this link, we'll both get a little extra storage.
