I purchased an AKASO V50x for about $60, a tripod for $15 plus a mini SD card. So, less than $100 all in. I narrow the field of view to 110 degrees to avoid the fish eye. I looked it up on Amazon. it's up to $85.
My son is a catcher, 3B and pitcher and it has excellent picture quality at up to 4K30fps. 4x zoom. I wouldn't recommend it for an outfielder.
You can find some really good quality cameras below $200. The reviews I saw on GoPro said that it was not good for baseball. I don't remember why, so I went a similar but different route.
I just googled best video/action cameras for less than X dollars and checked out the list and read the reviews. Just depends on how many X dollars you have to spend.
