Portable audio recording device

For a long time I have wanted a portable sound recorder. Now I'm at the stage to get one but...

The current models in my price range (< $500) Don't seem to quite cut the cheese. I've been researching it for some time now and I can't find anything good.

I need:
XLR Inputs (switchable between mic and line + 48V phantom power)
Digital recording (WAV & MP3)
Decent Built-in mics
Good volume Controls!

The Zoom H4 has really been my current pick, though it is a cheap device and it's operation reflects this with crummy menu driven controls for levels and input selection. Though the price is right and the features list almost fit.

The only other I have come across is the Marrantz PM660, though it isn't quite up to scratch with it's MP3 recording (only does it at 128kbps) and you cannot switch the XLR inputs to line.

Can anyone suggest another model that I have perhaps overlooked. The recorder is going to be used to record separate sound for HDV footage, sounds around society and nature (with built in mic), voice recordings, bands, etc.
