Good choice! Good luck, I hope you find one. I love mine and would never sell it. If you decide to buy new, The Ukulele Site gets them in. The uke will come well set up, plus you get to pick the one you want if you catch them early.
Dittos on that! I adore my AMM3 and it has spoiled me forever! I was completely lucky to get my AMM3 when I did; as fast as they'd get one online within hours it would be gone.
I recommend checking online ukulele shops daily and purchasing asap!
