I picked up a TrimUI Smart Pro with a 256GB SD card full of ROMs. I've had quite some fun playing what of these games I've tried so far. It plays everything from Atari 2600 to PSP. The Dream Cast games are particularly fun for me... It was $79.99 plus $30 for the SD card. It's generic, so I've ordered a Samsung 1TB SD card to move the stuff over to before it fails.
