X10 probes

I often find myself fudging up a resistor divider so I can use an analogue input on a Pro series analyser to look at signals above 10V.
10x probes would solve the problem nicely. In practice that might be 18MOhm (or whatever it works out to be) resistors in series with the flying leads in an alternate 2x4 wiring harness.
I wouldn't expect the x10 probes to have much above the current 24V rating as a safety thing (maybe 50V?). That sounds like wasting resolution because the full +/-100V range couldn't be used in practice, but the resolution isn't a deal breaker for most applications in any case.
