Yea I was just looking at those same ones yesterday. I've never used RF recievers and trasmitters, so I don't really know the difference between any of them. I was thinking about having a remote with about 6 IR leds (eventually upgraded to RF) for a wide range and using an Arduino 328 pro http://www.sparkfun.com/commerce/product_info.php?products_id=9218
and a 3-axis acceleromter, a thumb joystick from sparkfun, and aroud 4 pushbuttons about the dimensions of a wii-mote, and the case I could design in CAD class.A little ambitious for my level at the moment, but I would make one eventually. ;D
