Patrick,
I suspect the Unity 500 console is of no value to any of the NMR manufacturers,
though possibly you might get something from MRR or some other outfit for it.
The magnet should have significant value, if it has no problems (such as drift, a
quenched cryoshim, dewar problems, etc.) Siting shielded magnets is vastly
easier than siting unshielded ones, but if you have no problem with suitable
sites, I would recommend getting a new console, magnet stack/shims and probes
(and TMC legs, if you don't have them) for the 500 magnet rather than getting a
400 MHz system - provided you are happy with the magnet you have. Trade-ins to a
manufacturer basically provide a pretext for offering you a discount, which you
might get anyway; the really -don't- want the hardware back, unless it is fairly
new. Keep in mind though that you can place a shielded 400 almost anywhere,
which is clearly NOT the case for an unshielded 500!
