Just found a Sanyo es-p7 walkman with remote/headphones very good condition, excellent sound quality. Only problem batt does'nt hold much charge, looks like it was made for this unit, is this a rare find.  

I have an es-p7 battery. Yeah, it`s a custom one, though, other gumsticks will work.

I remember, getting in touch with sanyo. They said, that battery is almost impossible to get hold of.

These are interesting little units, a true one-off.  Don't I have yours Ric?

You do cris lad. There was a green one on fleabay, a bit since. I`m liking that sony tcm above.
