I would seriously consider getting the Zoom H2. I've been using mine for a couple of weeks for field recordings and it sounds like just what you're looking for. The on-board mics are surprisingly good and I've also used an external self-powered shotgun with no problems at all. The interface is very easy to use and the H2 is compact and light. The build quality is fine--it's mostly plastic, but solid and not creaky. Unless you're recording a very quiet source at the highest gain setting, the noise floor is acceptable. You do have to be careful with handling noise, but if you can keep a firm grip on the h2 and not move your hand around, you should be ok. For $200, I think it's worth ordering and evaluating--you can always return it if it doesn't meet your needs.
