The Betacom TA309 Ansaphone is excellent value. It is very basic and does not have the facilities that a more expensive model would have. It does record your calls but doesn't time or date stamp them. It is very robust (mine has been dropped three times now) and it comes with its own transformer and mini cassette on which you can record your own out going message. At just £14.99 from Argos it has to be great value if you just need something basic that will do the job in a simple way.
