I found a cheap PC Engine Mini on ebay. It is a PC Engine / SuperGrafx / CD-ROM system that contains 58 games. The menus can be set to English, even though it's a Japanese product. It sells on ebay for like 125 dollars US, including shipping. The US version – TurboGrafx-16 Mini – sells for 400 dollars US, plus shipping. No wonder why it's so expensive: The PC Engine Mini is the best system, cost-wise, because it basically comes with the same games.
Did you have any favourite PC Engine games? I am partial to Bonk's Adventure / PC Kid.
Too bad they didn't include the port of Strider. :(
