We recently, within the last month, bought new home phones. We decided on Motorola (sorry I don't remember exactly what model). We were specifically looking at expandable phone units because we have one specific room we wanted to add a phone to that didn't have a phone jack. These are great. You only have to have one jack to plug it into, and can have up to four additional handsets. The base unit also has speaker phone. All the handsets have a handsfree button which will turn them into speaker phones, or you can plug a headset mic into them (which our phones came with). They have call waiting and caller id. They have a programmable phonebook and you have the option of assigning special rings to the people in your phonebook. There is an intercom system between the base and all of the handsets. I am sure there are other features I am forgetting. In general we are very happy with the phones. We had been looking around for awhile, and finally saw these at BJ's I think the cost was about $140 for the base unit (with answering machine and one handset attached) and 1 additional handset.
