I've narrowed down my choices to the Edirol R-09HR and the Sony PCM-M10. Both appear to get a lot of praise, but I'd like to post a final question before I pony up the dough.

I'll be using the recorder for a fair amount of on-location interviewing, using the recorder with an external omnidirectional mic. In home, I'll run a mixer to it from multiple sources.

I get to use the R-09 at work for taping meetings, using the in-built microphones. The recorder seems suitable for simple conversations and interviews, and it seems durable enough.

Has anyone had issues with recording quality with an external mic, with either the PCM-M10 or R-09? From reading up on recorders, in general, it seems some digital recorders have propietary file formats. The Edirol doesn't have this, but I'm curious about the Sony.

Cheers
