There's a lot of good advice here, and patience is a virtue. We all know what its like to really want something you can taste it, and from my personal experience - buying it on installments or credit makes it taste - not as good honestly. A lot of us are talking from experience, and if we had a chance we would tell our younger selves the exact same thing: save your money, hustle a bit harder, and see where the best deal is.
This is a perfect opportunity to set a habit that can serve you well into the future. There are adults 2-3x your age that haven't figured that out yet. It was smart of you to ask, which tells me maybe a part of you recognizes it too. I'll promise you you'll appreciate it more when you've done it the financially responsible way.
