Has anyone had any personal experience with a Songbird hd made by Chris Foss?

I live in a very rural area and am considering making this purchase over the Internet, so I don't have the option of renting first, although that would be my preference.

I'll be a beginner hd player and am considering a 13/12 one. I've played music for many years, and I know this may be hard to predict, but I'm wondering if I'll be satisfied with this "beginner's" model. Is there a substantial difference between a 13/12 and a 16/15 (other than price;)

I am also considering Song of the Wood.

Thanks for your input,

Rose
