I've previously posted about the ultra-portable and cheap Zoom H1 from Samson Tech, which is a handy portable stereo recorder at an unheard-of $99 price.
The manufacturer claims that it will give you 10 hours of battery life on a single AA cell, and can accommodate up to 32GB of removable microSDHC storage. Its microphones are configured in an X/Y pattern for optimum stereo imaging.
I predict it'll be a hit for entry-level multimedia photographers, especially that it can be mounted on the camera shoe of a DSLR.
It's currently available at B&H which has also blogged about it. The post also answers the issue as to how to connect it to the camera shoe. The answer? Through a $35 male shoe adapter which is available from a different manufacturer.
I might just be tempted.
