And it would be pretty expensive too. Lab grade equipment, especially
in electronics, is very expensive as it has to accomodate for a broad
range of needs. Specialized electronics, even if it is a one-of-a-kind
thing and thus very expensive, is often cheaper because it is optimized
only for one case.

In the US, yes, not in Europe. Just try to find someone selling a
HP counter that is not 20a old on fleabay in Europe. While there
are a dozen in the US, there is at most one on the old continent.
If there is even one...
