A lot depends upon what features you need/want.
I used a $215 AU (new) Nikon L820 for years and it's great, but it lacks Mic input, flippy screen, manual focus, and eye viewfinder. All stuff that makes life a lot easier - but not essential.
So recently I bought a 6 months old secondhand Panasonic Lumix FZ300 off Gumtree (like Craigs list) for $225 (new price $680 AU) and still under warranty.
Is it as good as they say ? No it's not. Optically it's on a par with the Nikon, it has all the features I want BUT close up auto focusing is hopeless. I have to use manual focus - most of my video is within 1 - 8 feet. Apparently it's a well known problem.
So I find myself still using the Nikon as it's smaller and so much easier to shoot with.
What I'm saying is, more expensive isn't necessarily better, you don't need to pay a lot and buy new.
So my advice is to buy cheap to start off with (you can get an L820 for $80 ), just look for a popular YT camera that's on the used market and at the right price.
The FZ300 is nice, but not worth $680, even if the macro focus worked properly
.
A lot of the current cameras are really just re-hashed earlier models with a few upgrades, so don't be sucked in.
