Replying to Looking for a new camera

Ive been filming and editing for a few months now and I really enjoy it. the only problem is the camera I'm using is a 400$ one from sams club. horrible quality

im looking to upgrade to something a lot nicer. i have roughly 1700$ to spend, but I have no idea which one to buy. I was thinking about a panasonic dvc30, but I dont want to spend 1700 when i could have gotten a better one for 1500 or whatever.

please help me out. If it matters, I'll mostly be filming park and  urban with a little bit of night filming too. thanks alot
