I have the 3.1 and from reading my previous posts about it - its a great chip with truly no problems. Now a few friends want installs and are telling me about much cheaper chips out there. They are different versions of the Magic and I'm wondering - 'are they bogus, or what?' Please reply to this thread if you know anything at all about any Magic chips other than the 3.1 and share what you know. Should we really be paying a premium for one chip - when there are others that will do the same job? Thanks in advance for your reply. Ciao!
