At one time I was using some of the wire wrap wire to build things but soldered it in instead of goig the wire wrap way.
I looked on ebay and seems to me that wire is still sort of high as I would think like you said, almost no one would be using it now. Just about all the new stuff is SMD.
With the new software one can draw up the circuit and have a PC board made for almost nothing now.
A ham made a modification to the uBITX transceiver and would ship 2 PC boards that were about an inch square and had 2 or 3 transistors, resistors and capacitors for only $ 5 . Said that was about his cost.
Sure wish there were some local surplus stores close to me, but none around.
