Welcome to the Café.
Unfortunately there is no "best" beginners sax, but if you let us know what your requirements are, Café members can give you suggestions.
(Probably differing opinions, but that's the nature of the Café.
)
Some important questions:
- What size sax? (most people start on alto or tenor, but that is not necessary)
- Do you want a shiny new one, or would you be happy with second-hand?
- Do you have a budget?
If you are not sure what size sax, then it would be worth going into a shop that sells saxophones and trying out an alto and a tenor.
This sounds scary if you are a beginner, but most shop assistants are more than happy to help - just have a honk and wiggle your fingers to see if one feels better than the other. You may be surprised how much more you prefer one.
Rather than buying a saxophone straight away, you could hire one at the start.
Many shops will do this, or you could try here:

For what it's worth, my recommendation would be to get a second-hand Yamaha sax.
