I can rollerBLADE just fine, but obviously, I need to learn how to skate on quads!

For the next year, I just need a pair of skates so I can learn to skate. I don’t want something TOO expensive, incase I end up abandoning it. Can I get a decent pair or quads in the $50-$60 range? If I stick with it, I obviously would upgrade, but i just need something to learn on. I was planning on going to Dicks to buy a pair, will I have luck there?

Thank you!
