I'm looking at buying a portable digital sound recorder. I want to use it to record environmental sounds, music, noise etc to be used when I make slideshows from my photos. The only recorder I know anything about is the Zoom H4n. I have a friend who uses this, and have been pointed towards it by some retailers. DOes anyone have any opinions about this device, anything I should watch out for, or are there better alternatives, especially at this price as I know there are many much cheaper recorders.
