I predict that the FOIP webcam that Faceware will be selling will be pricier than most backers want to pay - I'm thinking it will bump around $200 give or take. To be worth the purchase, a webcam shouldn't peg above $100 I'm thinking. You can use cheaper webcams, but they will be plagued with no low-light capability and FPS speeds not to your liking WRT to FOIP. I've seen faceware's video and photos showing how much better it is in low light. Grain of Salt, imho
So, there's the Logitech C920 (discontinued but available for and C922 ($70-$80) - both very good but require a light source if you're a gamer playing in just monitor light. Streamers like them, but they tend to use studio-type lighting. https://www.bestadvisor.com/webcams/logitech-c920-vs-logitech-c922
ASccording to reviews, the C920 ($50 on Amazon) could capture 1080p or 720p at 30fps. The C922 Pro Stream ($100), however, can do either 1080p at 30fps or 720p at 60fps) (The logitech Brio is $200)
Razer has an option with it's own ring light (very nice for when you only have the light from your monitors) for $100 and it also handles 1080p/30fps and 720p/60fps with a 4:3 aspect ratio--> https://www.razer.com/gaming-broadcaster/razer-kiyo (order from Razer and it's free shipping)
