Talin, I crashed and cracked up my Z3 today and so yours is interesting. Quite luckily for me, B&H is selling a new Z3 for $699, but it may go off sale at any moment. I don't have too much time to spare then. How far can you go with this used Z3? I think an upgraded replacement for the Z3 is in the works at DJI, so prices are coming down, but the Z3 works for me cuz I am weird, I admit I'm not a power user. I don't want to hold you up, or insult you, but I'd buy your Z3 in a heartbeat for $450. Let me know what you think ASAP because for $250 more I can get a totally new unit at B&H ;-) Thanks for a timely response.
