Hi guys, I don't normally venture into this forum, but here I am. 
I'm looking to get a handsfree kit for my phone (HTC Touch HD) but have absolutely no idea where to start looking.
I presume I'm after a bluetooth headset thing.. something I can leave in my car, possibly charging? Not sure. Then when I get in the car, if I get a phone call, I can plug it in my ear, press a button and it'll connect to the phone, and answer the call with a further button press - something like that?
Sorry, I really have very little idea how these things work!
Again, I don't really know how much a decent example will set me back - but looking to spend less than £100 as an absolute maximum, cheaper is good.
Thanks for any suggestions/assistance!
