I saw the Rocketfish 2.1 Mini Bluetooth Module at Bestbuy for around $40.00
I got mine on ebay for $12.95 + $2.95 shipping!
Fits into your USB port and sticks out only a 1/4" (I have 4 USB Ports)
Has a tiny blue indicator light built into it to show you it's on.
I plugged it into my laptop, and Windows 7 automatically searched for the drivers, and i was good to go in a couple of minutes. I didn't even have to use the supplied Software CD that came with the Rocketfish.
Here is the info >

This way, if you purchase a new Laptop, you don't have to look for one with a Bluetooth Card built in, and spend $100 more for the priviledge. And if you already have a Laptop without Bluetooth, just plug this baby in and you're good to go
