Cheap audio surveillance device?

Question

Are there any cheap audio surveillance divice that will record for up to 24-48 hours of continuous audio.

Does not have to be anything fancy, a digital voice recorder that can record for 24-48 hours will do the job.

Answer 1

Small digital voice recorders are everywhere now.  Walmart, Radio Shack, Target, CVS, Best Buy.

Some of them record for over 100 hours.
