Ahem, thanks for pointing out it's great cost, as always it's the prices they're actually selling for, not what they're listed at that's important. I just bought a fully working 66311B for £100, but ago keysight tell me it's worth thousands 😁.
As I don't really need it, just wanted to add it to the standards, I'm happy to see it sold to fund inverted's TEA or given to someone who can make a better case for it!
