Has anyone decoded touch-tones off a phone line?
Modems can generate them, but I haven't seen any that can read them.

I know there are things like the Complete Answering Machine
around for $300, but has anyone hacked up (or bought)
something better (cheaper, mostly).
All it needs to do is tell me which key they hit.

Any pointers MUCH appreciated,

I never played with it but Radio Shack used to sell a DTMF (touch-tone)
decoder chip.  It's probably pretty easy to deal with if your handy
with such things.
