I recently purchased the following:
Linksys Bluetooth adapter USBBT100
Plantronics M3000 Bluetooth headset
The linksys bluetooth adapter has 100m range and works very well, i read a article regarding adding a antenna to increase tha range which i will do in the next few weeks, but once i had setup the headset to work with skype, i liked the freedom of walking around the house and still talking for free.
Widcomm Bluetooth icon

Microsoft Bluetooth icon
1. When you first connect the Linksys adapter, Microsoft Bluetooth drivers are automatically installed the Microsoft drivers do not support Bluetooth headsets.
2. Install the Drivers for your manufacturer in my case Linksys which will overwrite the Microsoft drivers
3. Go to Device manager and check the Bluetooth adapter, it should have the manufacturer of your bluetooth adapter and not Microsoft.
4. If you still see the Microsoft adapters, right click and disable the Microsoft enumerator
5. Now right click on the generic Bluetooth radio and click update driver
Pick > install from specific location
Pick > choose driver to install
Click > have disk
Browse to the folder or CD than contains the Bluetooth adapter drivers

7. Check the icon in the bottom right corner of the screen for the Bluetooth icon
8. Go into My Bluetooth places or double click the icon in the bottom right hand corner
9. Click Bluetooth setup wizard, then click Bluetooth service selection, find Headsets in the list, and the next screen will prompt you to make the headest discoverable, once this is done click search button.
10. Once found you may be prompted for a pin code for the device, put in the code and you will see M3000 Plantronics paired or the manufacturer of your own device.
11. Now go into control panel, Sounds and Audio devices, click audio tab and in the drop drown box labeled DEFAULT DEVICE you should see Bluetooth audio in the list.
12. Start skype, goto tools > options > sounds devices change Audio IN/OUT and ringing to Bluetooth Audio

13. Make a test call or check voicemail if you have this setup.
