I have the latest Mayflash adapter (from ebay), delivered in about 10 days to Cardiff (UK) so not too bad. I havn't tried setting up the rumble feature yet, but I'll have a go sometime and let you know on this thread how I got on. The device works perfectly with my official GameCube controller though, so if your controller is an official GameCube controller it should work fine.
