I'm using a Logitech C930e and I'm pretty happy with it. It's actually on sale on Amazon right now.
I guess the next step up would be the Logitech Brio which supports UHD (assuming you have the bandwidth and the sites you use even support it) which is right at the $200 mark. There are some good comparison videos on YouTube to help you decide if spending the extra money will be worth it to you.
