No Chi-fi? The Cowon Plenue D is still a very solid option, praised by many, solid as a rock, a 50 hours battery life with Hi-Res music, and only $176 in Amazon. Mind, it can only accept one 128GB SD card because of software shenanigans. Otherwise a pretty solid buy for somebody who doesn't want all the bells and whistles.
Chi-fi?The IBasso DX120 is another solid option, more powerful and better sounding, howver, the battery life only approaches ~15 hours Hi-Res, and its $300.
