You don't need to spend a fortune on needles, honestly; basic bamboo or metal ones from any craft store work perfectly when you're starting out. What matters is picking a medium thickness (like size 4 or 5) because they're easier to handle, and then grabbing thick, soft yarn like acrylic or wool blends that won't snag constantly.
There's tons of YouTube tutorials that teach you garter stitch and purl stitch, which is literally all you need to get going, so you don't have to pay for classes or anything. My advice is to start with something small, like a scarf or a kitchen cloth, something pressure-free; that way you learn the rhythm without stressing if you drop a stitch.
