This probe (it says Fairchild Scientific Instruments 106 on the cable) is a good 1x probe. I bit the bullet and tested it on a scope compensation signal and it has a slight overshoot but a very flat top on the trace. I'll use it for checking ripple and the like. It appears to be very well made and has cushy handle so I rather like it.

I should have been more specific. Actually I get about 9.3 MOhms on the 10x probe I checked. I am learning a lot though by thinking about this probe, reading everyone's comments and reading the various probe manuals available. Thanks for everyone's input.
I also ohmed out an old 1x Tek probe and got 300 Ohms. The center conductor on the cable is a tiny single strand of wire.

The publication on scope probes mentioned earlier is good and I am working my way through it. I already had it in my document collection and it was on my reading list.
If I ohm out a 10x 10Mohm probe in the same way, I get about 10 MOhms. I'll keep reading though...
I get almost exactly 9.00 MOhms on each of several different x10
probes within reach.
