Most compatible bluetooth PC card for XP?

[web1b]

I want to get a bluetooth PC card (for a laptop) that will be compatible with bluetooth synching with a Cingular 2125 as well as for tethering to the 2125 for EDGE modem access. It also needs to be compatible with Motorola HS850 bluetooth headset and have full functionality with bluetooth stereo headphones.

What are recommendations?

Got to be a PC card? I have been very happy with a BlueTake USB BT adapter. Has every profile under the sun.

I do have a Socket BT CF card with a PC card adapter, but it gets hotter than I am comfortable with so I don't leave it in all the time. It is older too so it didn't come with a lot of profiles, but I expect that is different now. I've always had good luck with Socket products. Don't know if the heat is particular to the card or the Tablet I had been using it in. Card didn't seem to get that hot when in the Dell X5 I bought it for originally.
