What should I do?

[(the) pterodactyl king]

I want to use Garageband and Logic Pro, and for that I am willing to buy an apple product.


So my question is what apple product should buy so that buying cost is the minimum and I can use those 2 software as well?


What should I opt for to keep the cost down but be usable for at least a few years?


I am not looking to create full tracks, just to convert loops and samples to apple loops format.
