... I'am a bit late but I'm definitly vouching for Kiff !
I've orderd some and they are really nice (especially the model with the LEDs).
And on the flat top models you can put the original black Nintendo Gamecube disc instead of the viper one, they are the same diameter and attachment.
a side note: on the illuminated model I suggest to clean the (simple) LEDs PCB, at least with a brush or a sponge to wipe off the very little bit of oxydation present on some cases.
Thanks again Kiff'
