There is indeed actually such a thing as "benchtop NMRs" (like Picospin, Spinsolve, etc. -- https://en.wikipedia.org/wiki/Benchtop_nuclear_magnetic_resonance_spectrometer https://en.wikipedia.org/wiki/Benchtop_nuclear_magnetic_reso...) but as you say they operate at a much lower resolution. (My understanding is that these machines came on the market for certain applications where the low resolution wasn't as much of a problem as other things like affordability or portability.)
