I think that anyone looking to find full-length videos of anybody is probably just going to have to buck up and pay for them. The sites that supposedly give you "free" anything all have a cost.
The best sites for some eye-candy are the free-tube sites. You only get a few minutes, but you can save a bunch and watch 'em one after the other.
I think any site that gives you free full-length stuff might also load you up with viruses...am I just paranoid?
