If you actually needed something (as opposed to wandering the aisles looking for stuff that might be useful: my garage is full of things like that), then it was worth it to pay the premium to have the fine folks at C&H sort and label things and put it out in a catalog.

It's that clip wire here and read ohms functionality that turns the PC into an issue. Boot program, plug in usb this, hook that to there is not the same as running a normal DVM. I can have 10 or 20 instruments in front of me on the bench. Having more than 2 or three on the PC screen is difficult.
