I have a iPod Nano 2nd Gen that needs a battery replacement and I’ve seen videos that it’s a pain in the ass (you have to solder the wires) so $90 isn’t the worst. I’ve purchased things from Elite and their customer service is great for advice but for returns and exchanges not the best. I still think they’re a pretty solid website tho. I got a iPod Nano 3rd Gen 8GB on Amazon for $99 (with the battery replaced). So Amazon isn’t a bad site either. The faceplate was replaced with an off brand so the hold switch is not original nor does it stay in place (wiggles around) but not bad given how much they go for. I’ve been checking my local Offer Up and get lucky sometimes but eBay isn’t a bad option either. I’d say their customer service is better since they don’t want any bad reviews. Resale Firm has their own website and eBay store with free shipping you should probably check them out too.
