Donny, I use the H4 and am very happy with it. It's has a bit more features than I really need. If the H2 were available when I purchased the H4 I would have opted for the H2 instead. I like the form factor of the H2 better. As for the H4 it has a feature that allows you using the built in mics to emulate a Shure SM57, Sennheiser MD421, Neumann U87 or a AKG C414. I don't have any experience with any of the above mics so I can't say the recordings via the mic really sound like they were recorded with the actual products. My favorite for recording via the mic is using the MD421.
The primary reason I bought it was to be able to record my voice coaching sessions and to listen to my practice sessions. It was well worth the $299 price tag.
