Handheld dynamic microphones tend to be much more rugged -- and less expensive -- than condenser mics, so they make excellent "first microphones" for kids and classrooms. Many USB handheld microphones offer the best of both worlds: a USB output for recording directly onto your computer, plus a standard XLR plug for connecting to mixers, amps, karaoke machines, and other audio gear. Just look for "USB and XLR" in the microphone's name.
