Good copy of Megillat Esther?

I’ve been invited to read the Megillah on Purim, but I don’t own a copy of it – I’d prefer to practice and read from the same book or scroll. Can anyone recommend a good copy of it to buy online?

Also, and I’m sure I can find this on YouTube, but a good ‘lesson’ or at least slow reading of the Megillat would help, as well, to get trope/cantillation down.
