So the ebay auction I had a man killed over was a lot of ipod classics with various sync issues, relatively cheap
The other component came in yesterday, a hard drive replacement
http://www.iflash.xyz/ you can also find them on ebay
It uses SD cards, MicroSD or mSATA drives
The process of switching things out was super easy, just buy the pry tool or opening kit
Fucked up the battery connector on one but I'm just an idiot
You can even install rockbox if you hate itunes
I understand why the dedicated music player market has died, it doesn't make me any less sad about it though
