If it's your first, take time to research well before you jump to make a decision. Compare options both when it comes to their cost and how heavy- or light-duty they are, when it comes to their features, and so on. There are even models sort of made for beginners, in the sense that they are easier to use so that you pick up the trade faster. I suggest you look here https://popular.reviews/leather-sewing-machine/ and on as many other sites as possible, you are the only person who knows what you need, after all. My only advice is to buy original and preferably one with dial stitch selection cause those are just easier to work with, in my opinion at least.
