Jim thanks again for the recommendation on the Sony PCM D50, I think it's amazing! Here is a video I did yesterday with it.
YouTube - Patrick Sise plays Bach, violin suite BWV 1001 Fugue
I used Pluraleyes to sync up the video and audio together. This software is a real lifesaver!

I thought you'd be happy with it. For the $$$ it's hard to beat. I think the clarity is much better than some of the other links you've posted and it does indeed seem to do a good job of showing off the high end of the guitar.

I think now it's a matter of experimentation with positioning and distance. Closer would be a bit better I think, but it might also interfere with the video if you wanted to keep the unit out of the picture. As with all things, it's a matter of trading off the various constraints to get the result that's important to YOU.

We'll be in Santa Fe week after next. If you're around, we'd like to stop by.

By all means please stop by!
