Hardware phone which works with skype? I've nerver seen such a thing.
Google is your friend.
A search for "skype hardware phone" (without the quotes) turned this up:
Results 1 - 10 of about 379,000 for skype hardware phone. (0.56 seconds)
So there's a few out there, methinks.

Here is the link to the phone I am getting myself:
http://accessories.skype.com/store/skype/DisplayProductDetailsPage/productID.106215900$99 isn't too bad of a price (well, for me). I know I can get them for as little as $25 locally if I look around and of course, it all depends on what kind of features, et al. you want.
I'm not sure where in the world you're at, but if you look in the Skype Store, they'll probably have something there for you. You can probably find it cheaper if you look around, of course, but this is a starting point.
I hope this helps some.
