I have VTech 2.4 GHz. Can put up to 4 phones on base station (I have 2 phones). It's cool. Phones look like one piece cell phones. Base has battery back-up (after you buy extra battery) so works even during power loss.You can get speakerr phone base or answering machine base. Phone have speaker phone built in so I have the answer machhine base (3 V-Mail boxes) Good sound quality. Very happy. About $129 for Base with one phone. 2nd phones are about $69.
Was highly rated in Consumers Reports. I don't use consumers for car ratings, but they are good for washers and phones.
-edit: VTech sounds like Zetec..hehehe....
