I use link aggregator sites (TwoMovies.tv is a good one) and look for links from thevideo.me or vidup.me—these hosts have downloadable options. (But be forewarned: you'll have to dismiss a shit ton of pop-ups in the process.)
There's also solarmoviez.to, where—whilst streaming—if you right-click/long-tap on the video frame, you'll be provided the opportunity to download. (File sizes tend to be much larger this way.)
And, of course, there's always torrenting...
