Great quality, but troubling design and fragile
I have been using the Tascam DR-40 for 3 years and the DR-05 for three months. I love the quality of sound from the internal mics on both these machines. I rarely use external mics now. But I am so frustrated by the need to hit the record button twice: first for paused recording, and then a second to actually record. In bright light, on both recorders, its nearly impossible to see if the record indicating light is blinking, solid or lit at all. I've lost hours of material by conducting entire interviews on paused recording. Perhaps I've been spoiled by Marantz field recorders, which have a separate button for pause and record, but when I hit "record," I would like to think I'm recording.
The second huge problem is these Tascams are terribly feeble when it comes to jarring when recording: entire files are lost if the machine is bumped or tips over on a table. I haven't found a way to recover these files without write-out. Again, I hate to compare to my Marantz PMD660, because it's so much bigger that it's kind of a different category--I can't carry it the way I can carry these Tascams nearly everywhere. But these loss of files are very serious drawbacks. Sad thing is no amount of reasonable professionalism or compensation helps beyond a point. The longer I use these machines, I know the more files and potentially great interviews I'll lose.
