Ok ordered an AceKard 2 for my nephew and put an old 4gb MicoSD card in. Works a treat, however a few minor niggles with the interface. I do prefer the R4 one when you select a game and if a cheat is available the box appears at the bottom. With the AceKard you have to select the rom then go into options and see if a cheat is available.

Also if you want to reset you first need to select the option in each rom, with the R4 you just made sure the button in the corner of the interface was green.

The build quality is a bit cheapy, no screw, just held together with plastic clips.

I'm just being picky but these niggles aside, it works great and is so cheap so I do recommend it.
