For anyone trying to get into speedcubing, I'd recommend YouTube tutorials from channels like J Perm, especially his Beginner Method tutorial, which I found taught me much better than any written resources I was finding. He keeps the alg count lower at a slight cost to efficiency, but this makes memorizing it a lot easier, and you can still get solve time down to a minute or two after enough practice.<p>For learning Roux method (my favorite), I found CriticalCubing's videos most helpful, though Kian Mansour is also quite popular, and SpeedCubeReview has some Roux videos as well.<p>For the actual cube, check out which cubes under $15 are popular on speedcubeshop or an equivalent online store in your country. I haven't bought one in a few years, but the MoYu RS3M 2020 and 2021 were both quite good. I would recommend picking up the extra magnets to add in, and a bottle of cube lube (as silly as it sounds, it keeps things working well for longer, and you only need a few drops). Generally the Rubik's brand cubes are seen as worse than any modern Chinese cubes (patents expired a while back).
