Starter shamisen for smaller hands

Hi all! I am a new member here looking into getting my first shamisen, and I have questions related to neck sizes. I have been debating between getting the Beginner Shamisen or waiting for the ShamiBuddy to come back.

I am a small person with small hands. For reference, I can span an octave on white keys on the piano, but a ninth becomes an uncomfortable stretch. I want to be able to explore different styles with my instrument (tsugaru, nagauta, minyo, everything). Does anyone have experience with this particular issue affecting how you play and the instrument you buy? Are there issues with style vs. neck size? I would appreciate any insight.
