Thanks for the update. This model appears to be similar to the Sanyo model sold in USA as the Yamaha Pocketrak 2G. They are the same size and weight. There is no WAV recorder smaller than this pair. In comparison, the R-09HR is more than 3 times larger and heavier.
The updates include the three mics (vs 2 in the 2G), slightly redesigned button placement, and the addition of the microSD card slot. Both models record only 16/44.1 WAV files, and both run on a single AAA cell.
The Pocketrak 2G cost $400 when introduced in Spring of 2008. Now it's available for less than $200, perhaps to clear out inventory so the new Sanyo model can take its place.
Sanyo makes a large number of hand-held recorders. Among these, my choice would be the Yamaha Pocketrak CX ($300). It's about twice as large as the 2G, but its controls are easier to use. You need small fingers to control the 2G without looking closely.
