I have the Hifi Walker H2. It's made of metal and has Burr Brown audio chips and can also play hi-res audio. I play FLAC most of the time and the sound is amazing if you use good in-ears. Battery life is great. No Android, but can show album art and lyrics. You can also play audio from your phone via bluetooth. Playlists are possible. Left/right balance and equalizer. I have a 250Gb card to expand the players memory. (Someone wrote he's actually using a 1Tb card)
(I paid 125 € from Amazon Germany)
