Which is the best recommended answering machine out there?

[broadwaymiracle@xxxxxxxxxxx]

Hi everyone.  I'm looking to buy an answering machine which must have
the following two criteria:

*2-way recording (ie.  records not only incoming messages when I don't
pick up the receiver but can also record BOTH incoming or outgoing
calls to my phone) with at least 30 min. of recording time/with good
quality sound

AND...
*some way of getting/copying/saving the conversations off of the
machine onto other media (CD etc.) so I don't have to worry about it
getting over-written by new messages if it's something I want to save.

Does such a machine even exist?  I know the first item is found on many
digital answering machines these days but I have yet to find the 2nd
feature.

Gone are the days of answering machines which used cassettes... I
wouldn't have this problem right now

Thanks and hope to hear from someone soon!
