Yeah, you gotta try some first, and buy used if at all possible because as you progress your needs will change.
Is there a SUP club near you? Do you have local stores that will allow you to demo boards? Are there local FacePlant SUP groups you could contact to see what is available?
The depreciation on new boards is too steep to buy them without first trying them, and comparing them to others.
Now, somebody will be along in a moment to recommend the starboard All Star. But do please try some others. As with surf SUPs, race board choice is very personal, and the right choice depends on your own style and strengths (as well as budget).
