Bought it, used it, hated it, sold it. Sub-par on every level, even when compared to clone systems rather than the real thing.
The d-pad and buttons are amongst the most abysmal I've ever used. Many times it simply does not respond to your button presses, period. The screen is not the same, and everything looks *bigger* (but not in a good way) from the actual GP. Skewed. It has trouble playing original carts...once you pull it out and put it in 10 times (yes, that is what she said) and it still doesn't work, you'll just want to throw it against a wall. Oh, and it doesn't take GB or GBC carts like an actual SP does.
I imagine the only reason they wholesale them now is because overall the product is a flop. Great idea, poor execution. Seriously, it is not worth getting a group buy on the things going...you can get an actual SP for a lot less, and then the flash cart of your choice. The K1 Card is no more capable of a flash cart than the EZ IV, and that's pretty widely available for about $25.
