Register at Amazon! I love it, it's like my second home.
But if you plan on buying anything online, you're going to have to give them your info.
For an inexpensive microphone, look in eletronics stores.
The microphone in your link is $18. My
headset cost $15 at Wal-Mart and it's functional, works for me just fine and one of the cheapest ones you can find. Or at least the cheapest one
I could find.
