Be wary of "voice" recorders if you're really interested in producing audio slideshows with more than simple narration.
Voice recorders are made for recording voices at close range, and after experimenting, I've found that they are poor at recording ambient sounds or music, or even voices from farther away than a couple of feet. Sonically, voices are limited in their frequency range and dynamic range, so these recorders can get away with recording at limited frequency ranges and low bit rates -- if they are used for what they were meant for -- dictation and transcribing.
If you want good nat sounds and music recordings at live events, you need a device capable of reproducing a much wider range of sound.
If your serious about telling stories with multimedia, I think sound needs as much consideration as images -- the two work together, just as words and pictures work together to tell a larger story. If newsroom managers or bean counters balk at spending a little extra on a decent quality recording device, ask why you would spend thousands of dollars on camera equipment to make high quality images and not spend $200 to make decent quality audio? Web site visitors will tolerate poor quality for only so long. They will become technically savvy, too, and won't sit through a slide show with crappy audio.
The H2 is a good starting point. Google "portable digital recorders" and you will get an idea of what's out there, what the different features are and which ones are important for journalists.
