Rastasean-If you want a recorder with phantom power, I'd recommend the Fostex FR2-LE over the H-4. I love mine and everyone on taperssection who has one seems to like theirs (especially if modded by Busman, but it's supposed to sound good stock). Note that the Fostex's internal mics are worthless, but with externals, it is a far superior recorder to the Zoom.
If you plan to tape with mini-mics and stealth is important, get an R-09. I'd be leary of the Microtrack II, unless you want to use it as a bit bucket.
If you really want a Zoom H-4, I have one gathering dust. Maybe I could make you a deal if you also want an external battery and Sound Pros' adapters that allow you to easily use mini-mics with it. It worked fine the few times I took it in the field, but it is not very convenient to use (unless you want it for it's internal mics) and has a number of reported problems when used for taping live concerts.
However if you're serious about taping, I don't think you'd use a Zoom for very long before you'd want to step up to something better.
