Depending on what level you want to do your commentary on, I'd either suggest a cheap stand-alone microphone like the Logitech USB (which I have) as it offers far better quality than most headset mics.
The Blue Yeti is very common with amateur Youtube commentators that aren't willing to go into professional equipment but still want something that differs from the average. I believe it goes for around $80-100, and is a bit overpriced considering that it is a USB computer microphone. For that price I would probably look into a sE Electronics 1000A (condenser) or Beyerdynamic TG V50d (dynamic), which are borderline professional microphones that goes for around the same as the Yeti, however they do require that you have a proper recorder (putting the total price far above the Yeti).
Beyond that is out of my knowledge range.
Also mind that high-quality microphones pick up a lot of ambient sound, details, textures and so on. As such, you need to work with the raw recording to cancel out all the noise and extra sound, but with some filters a quality microphone sound by far the best. Oh, and make a cheap pop-filter out of a pair of pantyhose and a circular frame.
If you want cheap, get a Zalman clip-on for like $5 and go with that until you feel the need for something better.
