STTP: Which Bluetooth dongles work well in Vista?

Hello, I'm new to this 'group. Using Windows Vista Home Premium.

I've been searching the WWW for Bluetooth dongles. More or less all the
ones I find claim to work with Windows XP among other versions, but don't
mention Vista at all. A search on Google for "bluetooth dongle vista"
brings up many forum posts from people who are having nightmares getting
their devices to work.

I would like to get it right from the beginning, by getting a model that I
can be sure works. Preferably straight out of the box, by Vista's own
driver or a driver that comes with the device; failing that, something for
which getting a compatible driver and getting it up and running isn't too
much effort.

Somebody mentioned D-Link DBT-120, which I've found here

http://www.amazon.co.uk/D-Link-USB-B...dp/B00006B7DB/

but at £25, by no means the cheapest. Another one I found is

http://www.bluesoleil.com/products/i...o&id=115319003

but this seems to contradict itself on whether it's Vista-compatible.
Besides, that site has extortionate S&H charges.

What models have you people tried and found to work well with not too much
effort? And of these, which would you actually recommend?
