Plenty of these threads about to pop up I think I am open to the system type, I would prefer a clean system (no yellowing on pc engine) with a power adapter included. I do not need a controller.
Truth be told, your best bet right now is to go to ebay. You'll be fighting others on here for them at this point. Not trying to dissuade you, but for the short term it might be a better option honestly.
In the same boat. If you're willing to go with gamer's condition, they're not too bad on eBay, but way more expensive than I thought they'd be. Most are in Japan (as you'd expect), so shipping is a killer.
