All you need is a spindle and some roving. It's fantastically simple!
It's nice to have a niddy noddy, but I spun for a while without one. I looked at them at the spinning store and I was all
at the cost...I headed over to the hardware store and made a PVC one for under $3 :D
Things like combs and cards aren't necessary unless you want to prepare your own fiber...it's probably best to see if you like spinning first! And if you do, you'll want to start saving for a wheel right away
