What I want is to record a stereo input signal on a USB drive or SD card, without the use of a laptop.
The reason is I play in a rock band, and during rehearsals it would be nice to be able to record the output of our mixing device. We don't need all 16 outputs, just a simple stereo mix will do (we have mic-ed/lined all singers/instruments).
I want a cheap solution (otherwise I can bring my laptop), but I see many dictaphones with microphones builtin, but not with a (stereo) audio input.
