It's worth it if you do this a lot. The Micsig ones aren't expensive for what you get.

Speaking of Micsig: My STO1104C came with four fixed 10x probes. Smart decision, IMHO.
TomKatt:
As mentioned, I have a Micsig DP10007 10X/100X differential probe - it's just that I understand it to be noisier than conventional probes, and noise/distortion is exactly what I'm investigating.

I'll probably pick up a set of fixed 10X ProbeMasters at some point - they are really nice and have the best set of optional adapters I've seen for probes.  But it's not often I measure voltages approaching my scopes limit.

Re-check it after you've had visitors. Or every time you pick it up if there's children around.  :)

Or there are cats around.

Or - perhaps especially - if there is you around. Don't ask me how I know; you would get an essay rather than a bullet point :(

Oh, you only mentioned the 10X, so I assumed. My bad. I have 4 fixed PM 10X probes. I'm going to get a fixed 1X probe or two soon. I don't like the switches, not because of their quality, but because I don't want to be able to forget what position it's in. 😉

Yeah, if I had it to do over again I'd probably have got 2 pairs each fixed.  Oh well.
