Question Question Regarding Vacuum Pumps

[VamonosPest]

I'm currently planning to do a vacuum distillation to make some methylamine,
i am unsure which vacuum pump to buy and how powerful it should be and i don't wanna break my glass
because of too much vacuum.
I'm thinking of going with the brand VEVOR because the are cheap
but my question is which one of them should i get?
and are there anything else i should take into consideration?
