I haev a Zen Touch, and love it, I'm looking for something smaller, but not muvo size. Something with atleast 1.5 gb, and small, but not a slit screen, more like a full box screen.
I had in mind the Rio Carbon, and the Rio Ce2100, but I only find them refurbished and with little warranty.
I'm also looking at the Philips HD070, but I dont have any feedback on it, I want to keep it under 150, other wise i could just get a zen micro for $180.
