I have the Zoom H4 and can vouch for it's usefulness. I bought it for a whole raft of real and potential uses, including recording at my band's practices. I've also used it in a number of low volume (church) and high volume (Australian Grand Prix) settings. I haven't yet had call to explore it's more involved functions such as an audio interface, the 4 track recording, the inbuilt effects range, etc. Basically, it's a winner. Controls are weird and not particularly intuitive, it feels and perhaps is flimsy and plasticky but does record pretty well. The capacity to record in a wide variety of mp3 kb/s rates (up to 320 from memory) or wave file to 24/96 is impressive. I recommend it but think the new Zoom H4n is significantly better again and solves some of the od little design compromise issues with the H4 (bigger, clearer display for geriatric old eyes for instance). The H2 would work for you I'm sure but I'd be inclined to spend the extra and get a bit more future proofing by going with the H4n. Check it out at the Zoom site. Good luck with whatever you decide.
