I was quite surprised as well!
Assumed it would go high for a 20, but when deducting the value i would have set on a standalone Omega generator, there´s still enough left for a nice Jensen 50.
However, it is extremely rare seing a powerplant with this generator.
So if i was aiming to complete a collection, getting close to it and had the funds available, i would most likely have gone "all in" as well.
No telling if another comes up within the next decade...eventhough this impressive sale does help raising the chance that one or more will.
