Samson Q2U is an excellent option if you are on a budget or you needed a larger setup for 4 or 6 people. Having both XLR and USB connections, it is extremely versatile, allowing you quickly change your setup depending on the type of audio content you are recording. This mic sounds really well and can easily compete with pricier USB mics.
Shure MV7 is the best USB mic for podcasting. It can use an XLR connection if you need more flexibility (e.g., mixer connection). It sounds rich and wonderful. The built-in headphone output allows for direct sound monitoring while recording. Multiple controls on the mic body (mute, gain) allow for flexibility and use for collaboration.
Audio Technica 2020 USB+ is a well-rounded mid-tier USB podcasting mic. It comes with a small tripod for a quick start (not my favorite part of it). It sounds well and provides good quality. Remember to put a pop filter on it and record in a rather quiet place. It also has accessible controls directly on the body and a mic jack for direct audio monitoring.
