First I would like to apologize for posting this question on Apple-related stackexchange site. I looked at all stackexchange sites and it seems that this one is the closest to the topic of my question. If however you know of a more appropriate stackexchange site, please let me know and I will move my question there.
So, as the title says I'm looking for an inexpensive mp3 player, hopefully around $80 and below, that runs on AA or AAA batteries, preferably AA, and that has an SD* card slot and also supports SD* cards of at least 32GB. Doesn't matter if it's SD or microSD, SDHC or SDXC, I just need the 32GB minimum support. Internal storage could be 1GB for all I care.
Multiple format support like FLAC, AAC, Vorbis etc is not necessary.
It is pretty hard to find AA or AAA powered player nowadays, so a player that has a replaceable internal battery, preferably with one that nokia uses in its cheaper mobile phones would also be ok.
My current option is going with Sandisk Sansa Clip+ with an external AA charging thingy like Tekkeon, but this setup is a little clumsy in my opinion, so I would first like to know if there are other options.
This player is going to be used every workday of the week, for at least 8 hours. It is a replacement for a dying discman.
So if you know of a player that meets the above criteria, please let me know.
