Definitely get a camera. If people give you shit after buzzing you, point to the camera and say, I've got your plate. Shuts them right up. A cheap sports cam with a bike mount costs about $50. About the same as a new helmet, and just as necessary if you're out on the road.

A dash cam is nice in a car, but it's vital on a bike.

If you don't insist actually having a GoPro brand GoPro, they're pretty cheap.

how cheap is cheap? i have a hero3 and have beat the crap out of it and its still working. you can get refurbished one on amazon for $140 here
or you can get a knock off for $52 here

if you are going with a 3rd party i would stick with the knock offs that are the same basic shape and fit the go-pro accessories and cases, so it will fit the derby made cases and mounts

~$55. These are a great deal.

If you're not in a hurry, you can find dash cams on Wish for like 10-15 bucks shipped. https://www.wish.com/search/dash%20cam/product/5c66534e6730fb55ed55615f?&source=search or https://www.wish.com/search/dash%20cam/product/5c21a8a66173582d1f7ec06e?&source=search

I'm using a GoPro knockoff from Amazon that I think was like $30. This one: https://www.amazon.com/gp/product/B01MXXP4EC/ $32 after coupon applied. The sticky pad for mounting sucked ass, so I got a 3M mounting strip that's been holding on for a year now.

edit: i missed the part you ask for high quality. obviously my suggestion is not that. ill leave it here for people looking for budget camera!

I've been using this cheap camera from amazon for a month now. Quality is so-so but should be enough for insurance purposes. Havent had much issue. I also use a USB charge bank plugged into it so it doesnt die during long rides and i never have to think about charging it

Great sound for starting out! Keep it up and you'll gain a following in no time. I'd recommend a few things to really make your videos more professional. You may not be able to afford all these things right off the bat but save up and eventually invest. It will pay off.

1. Lighting - Grab a couple of soft box lights and really light up your scene. They're very cheap now and days and allow a more expressive video to be captured and color corrected.
   
   
2. If you're not already, use a DSLR camera to record yourself and each individual instrument. A high quality video can make a world of difference. I saved up and bought a Panasonic Lumix G7. It's perfect for entery level / mid-range YouTubers. Interchangeable lenses, 4k/23.9fps, and 1080p/60fps.
   
   
3. Get an action cam. It doesn't have to be a GoPro but can be a cheap knockoff. As long as it can record in 1080p at 60fps you'll be good to go. I bought a knock off one for $50 a few years ago. With this camera, you can them clamp it to the neck of your guitar for a unique view you can cut back and forth to while playing.
   
   I think if you tackle these steps first then you can go on to improving even more. As a content creator, you'll literally NEVER stop improving and that's perfectly fine.

I got this one saved on my amazon: https://www.amazon.com/gp/product/B01MXXP4EC/ref=ox_sc_sfl_title_21?ie=UTF8&psc=1&smid=A7D3NM94RJOFC

Plenty of great reviews, and fits gopro stuff.

I'll be getting this for my helmet when I get my bike.

when you consider you can buy 4k cams on amazon with SONY sensor for 50 bucks or so, it's inexcusable. I GET IT that CANON wants people to spend MOAR MONEY for the high end video product and doesn't want to cannibalize sales but don't tell me that you can't design a BASIC level of functionality it into your product right now.

Until I upgraded to a GoPro for other reasons, I used one of the Amazon knock offs like this with a chin strap mount like this since I didn't like the idea of leaving something permanent mounted on my helmet. If you don't care about that, then using something like the sticky mounts or Sugru on your helmet is probably more stable.

Other options you might want to consider are using a chest mount to make the image a lot more stable. You might also want to check out a backpack strap mount for convenience.

Attach a camera to a high altitude balloon. We did this at school and you could conceivably do it at home. You can clearly see the curvature of the Earth in the pictures it took. You can get a balloon for like $60 and a knock off GoPro for $50.
