Limoncello?

Hi! I [21 F] want to make limoncello for my family as a christmas gift. This is my first time making any sort of alcohol and I really don’t have much experience with it otherwise. First of all, I definitely can’t afford a 100 proof vodka to make this unfortunately but I found some 80 proof ones that will suffice. I have no idea which one I should use. Some of my family members are very well versed in alcohol quality and I don’t wanna pick a random cheap one if it’ll affect the finished product. Does anyone have reccomendations on which vodka I should use to make this?
