Inexpensive Liquid Nitrogen Generator

This is an undeveloped idea, but I wanted to test if there was any interest from other members.
Liquid Nitrogen is a common low temperature coolant. It's particularly useful for high temperature super conducting ceramics. While it is commercially available for useful laboratory purposes (lab that I work at uses two to three dewars a week) it is still too expensive to consider for any 'consumer' products. From talking with our supplier, the equipment to generator liquid nitrogen takes several (5-10) years of use before turning a profit.
Though there is little consumer demand for cheap liquid nitrogen, making it available seems like it could be a compromise for allowing widespread adoption of superconducto applications without any new fundamental material research.
Any thoughts? Is a low-cost (as in hundreds of dollars) cyrogenic system a feasible project?

Okay cancel this, just got a new cyrogenics catalog and after amortizing costs on a new generator LN2 is cheaper than milk. Guess is was a good problem because someone solved it. Let the superconductor revolution begin.
