I make pasta as often as I can, but we buy it, too. Well, not a lot, we probably eat pasta once a month, maybe.
If you're goal is to eat the best, cleanest, and most nutritious food available, then making your own is worth it. You can do it with a rolling pin to give it a try, then buy a machine if you think you will make it more often. I have a hand-cranked machine, too, that I have had for....um....decades, and it works great for the small amount we eat.
If you have a stand mixer, you can get an attachment, too.
It is very simple....flour and egg. I use whey and ferment the dough when I make it. Makes it more readily digestible and even more nutritious.
I like to use kamut. You have to handle it carefully, as it is fragile when dry. I just store it, loosely packed, in a glass jar and only make the slightly wider noodles and lasagna noodles since kamut makes such fragile noodles. They are absolutely delicious, tender and mild.
ETA: oh, and I grind the kamut myself and use a food processer to mix the tough, heavy dough.
