broken gamecube

[Olimar is Down]

I'm getting a repeating message saying that my US GC cant read teh game disc.
Its happening on VJ and SCII and loads the games fine but then just happens every minute or so.
Is it a drive or a laser prob, and is there any point fixing it - or shall i just get another cube?

Apparently Saurian is the man for this??

Cheers
