It depends on your computer:
IF you have an audio input jack, then you can hook up any external mic.
If not, you'll need a usb audio input adapter (Griffin's iMic is the cheapest solution here) to plug the microphone into.
But unless you place the microphone far away enough, you'll still have an echo, because the microphone is just picking up the noise coming out from your speakers... a better microphone might just make this worse.
I'd get a headset...
the audio-in would be a simple solution, but this just means that you would need to not only buy another mic, but also get the
imic from griffin , which is $40 itself... Another downside is the audio quality - when using the audio input jack your using analog audio.
The best solution if you dont want to use headphones and or get two seperate devices would be to go ahead and get a usb mic/headset from logitech. i know the one for the ps2 which is usb based works on the mac - i once used it on my ibook, and it goes for around $25-$30. Any other generic usb based headset would work too...the good thing about the usb based headset/mic's would not only be that you dont need to buy two seperate devices, but the audio quality is better too.
Take a look at the
Logitech Headsets. They havent gotten too much into the usb run of things, but there are other out there..plantronics, panasonic, etc.
