When I do a Mouser search for frequencies in the range I mentioned, the number of frequencies is pretty small. If I switch over to looking at crystals at Mouser, the frequency choices are a lot greater. Yes, as with the oscillators you need to sort out the ones that aren’t going to cut it. To your point - no, you can’t get anything / any frequency through distribution. That’s true both of oscillators and of crystals. You just more picks with the crystals.
