Amazon Fire TV (are they worth a lot of money?)


Erm, bit of a long shot, but does anyone know if the Amazon Fire TV box (ver. 2) is special in some way? The reason I ask is that I’ve just had someone bid my second hand one up to £75 on eBay, when you can buy the new model for £55??? I’m not expecting to get paid tbh but wondered if they were sought after in some way?
