Having visit youjizz for some time I have become impressed with the improvements they've made in the last year or two. Sharing content with the site jizzhut (and potential other, I don't know of) they increased the length of their average clips from 2-4 minutes to 20-45 minutes. And they always have new content, although you can tell when they get on a genre kick because there will be a lot of a certain kind of porn. Registering for an account is free, and you can save (but sadly not search) your favorite videos which is awesome!
