Thanks for all the information. My hair hurts from dealing with all of this.
Still trying to make the right decision on the recorder and mics, while keeping the budget down to make sure I want to continue with all this. So the options remain:
Tascam DR-05, with Rode VMP and inexpensive GS Omni mic.
Tascam DR-40, with Rode VMP (plugged into the Rode XLR adapter) and possibly a Oscar SoundTech lav, which I recently discovered and which may be a good choice, both price-wise and quality-wise plus it can be ordered with an XLR connector. I’m still not sure if the GS Omni mic can be used with the DR-40 if it is plugged into one of the Rode XLR adapters.
I’m leaning toward the DR-40 option, based not only on the comments here but from fellow photographers (who like the somewhat similar H4n).
Any other comments/suggestions.
