New user for apple macbook

Honestly, your budget is low to get an Apple refurbished MacBook Air or Pro: https://www.apple.com/shop/refurbished/mac/macbook-air-macbook-pro

Your can buy used Macs all over, but you'll be better served if you stick with Apple for refurbished units. Each has the full one year Apple warranty.

Look into the Mac mini. This was my first Mac computer purchased in 2011 and it is still going strong. Even working better than windows machines that are half the age of the mac. It’s affordable and can easily be moved locations or even taken on trips to connect to a tv. Cheers!
