This seems to be the cheapest price that the C64 Mini has been posted for here on OzBargain. Postage seems a bit high without Amazon Prime, so this deal is probably only good for those with membership.
Reviews for the C64 Mini have been mixed but at this price you surely can't go too wrong. Alternatively, you could always set up something similar with a Raspberry Pi.
Specs:
* High definition output at 720p via HDMI
* Pixel Perfect display, with US/Europe display modes and crt filter options
* Save game function. Supports software updates via USB flash drive

Why oh why couldn't they make the keyboard functional?
