Isn’t it not the best idea to buy it on eBay?

Yeah at that price point, the Pro would be worth it bc the upgrade is worth more than $200 imo

Someone else can correct me if wrong but imo the deal for the base M1 Air for $750 is the most value. Depending on what you’re gonna use it for, more ram or storage could be needed but if it’s just non intensive tasks then base model should be fine. Not that big a difference between M1 and M2 from what I understand
