Get the Turtle Beach PX22. I just got mine this week. It's awesome. Sound is perfect, big speakers, it's got adjustments for bass, treble, voice chat, game sounds, etc. Mic is really good quality with multiple options. Very simple to use. 80 bucks, so not the cheapest, but it's compatible with the PC, Xbox and PS3. If you want an all-around headset for under 100 bucks then definitely get it.

It comes with plenty of cord, so you definitely will have enough unless you game in a movie theater and like the back seat.
Bottom line, it's not too expensive, reliable, very good quality, compatible with any console, PC, or cell phone with a headphone jack, and it's easy to use.
