Honestly there's no point in going all out on everything right away imo. If you get a cam caddie for 20 bucks, generally the weight of the camera keeps it pretty damn stable if you hold it right and aren't hitting a ton of death cookies while skiing.
Idk. I don't know much about anything but I feel like sometimes people in here will push the best gear when it isn't necessary. Like some tripod threads where people will tell you that anything under $3,000 is a waste of money and completely worthless.
Obviously there are definitely things that are worth the extra $, but just because things aren't the most high end doesn't always mean they're trash imo.
Also you can transfer accessories between cameras. Maybe you decide to get a more expensive camera down the line, if you bought a mic, glide cam, even lenses(if you stay with the same brand) you can transfer them over.
Maybe I'm just cheap for this forum.
