You can't really escape the physics here, you need a very strong and very homogeneous magnetic field for NMR and very sensitive electronics to detect the signal. That's not something we can do for cheap right now.

And even beyond that I don't think the area has enough volumen and is competitive enough to produce significantly lower prices. The high-field NMR area is almost a monopoly right now, the benchtops and lower field instruments are somewhat competitive. But even those are in price areas far beyond someone doing synthesis at home.
