We have tested against _lot_ of SIP hardphones. Most of them can speak SIP quite well today, so the decision making process relates to budget, stability, and features. Cisco telephones have always been the most stable ones. Unfortunately, the most expensive as well. 7905s ship now which are cheaper. Grandstream is certainly the most affordable SIP telephone today and it supports STUN nat-traversal (it ships through sipphone.com). Mitel is a very convenient phone (like Cisco, it features 3-party conferecning, for example), I just sometimes experience voice distortions which are possible caused by the telephone. pingtel is another one of the good-and-quite-expensive class. We have not been approached by polycom for testing their general-availability phones so I don't have any opinion on them. There are some other sip phones too, but we either never got them for testing or they are better not worth mentioning.
