I need to buy a multimeter. I noticed that for the resistance some
have 2000k and some have 20M, which I believe are totally different.
Which one is better to have? Or does it even matter? I'm mostly
interested in testing something that's around 2M. So I don't know if
it matters which multimeter I get.

For resistance measurements, more is better. A short circuit is ideally
zero ohms, and it goes up from there.

Practically speaking, you might never need to measure more than 2 MegOhms,
which is a high enough value for most uses.
