A company in the UK is working on a multithrust rocket/launch vehicle that would be reusable. It mixes a super-cooled jet engine with a rocket booster. For once you get beyond enough air pressure for the jet engine.

Something like this, that's reusable, would allow small (but larger than cubesat) payloads into orbit for what should be a reasonable price. 200 launch lifetime on the vehicle is the plan.
