Welcome to the recommedations section of 3x3! There are 3 levels of cube recommendations, Beginner, Intermediate, and Professional. In these levels, there will be cubes that are recommended from me.
Beginner level cubes:
The Legendary MoYu RS3M 2020
Price: Usually $8-10
This is the legendary MoYu RS3M 2020. It's a best seller on many cubing stores, and is the best budget cube. It is magnetic, so the layers align, making it turn better than a speedcube without magnets.
I would highly recommend this cube, as it turns good, and isn't pricy at all. If you are new to cubing, and are trying to get a good cube, get this!
Here's a few more great cubes, in the beginner level...
Price Range: $25-$45 (Variant Depends)
The X-Man Tornado V3 is one of the best cubes I'd recommend for beginners, it has good features, performs well, and the price is fine. There are 4 versions available currently, the standard, the flagship, the pioneer, and the pioneer uv. The cube has adjustable magnets, and a hand-tuned tensioning system. In my opinion, I think that the Flagship version is the best variant out of all.
Price range: $8-$25 (Variant Depends)
The MoYu RS3M V5 is one of MoYu's budget flagship cubes. The versions are standard, standard dual-adjustment, MagLev, and MagLev Ball-Core UV. I main the ball-core UV version, and it's very nice. At a low cost, it makes it even better. The MagLev is just right, and the magnetic core keeps the cube stable. I'd recommend this cube if you're looking for a budget flagship cube.
Price range: $17-$20 (Variant Depends)
The DaYan Guhong Pro is a great choice for any level of cubers. The price is very low, so that's good. The standard version costs $17, and comes in 3 different sizes, 54mm, 55mm, and 56mm. The standard version has a magnetic core inside, which stablizes the cube, and gives a better performance. And for $20, they have a MagLev version. The Maglev version has a magnetic core inside, + maglev, it's a great package! I'd definitely recommend this cube to any level.
