I've been using my Edirol R44 more and more lately, and still like it a lot in most respects. However, the screen is small and the metering, which uses less than half the available width, is inscrutable. The closer you get to 0 dB (full scale) where you really, really need to know what your exact peak levels are, the less you can see. Also, its continuously variable input level controls are always in the circuit, and have no detent at the point of unity gain.
But the design gets just about everything else right, for my purposes at least. I definitely like being able to stop recording, have the file be saved automatically, and start a new file all within a second--something I could never do when I recorded everything on a laptop computer.
