So I finally bought an iPad (just got an iPad 2) and the little thing is so much fun! Been messing around with GarageBand (which is a helluva lot of fun for this weekend warrior hack, btw) but need a way to connect my guitar to it. I've seen that iRig and it's cheap, about $30, but have also seen that one advertised in the new iPad 2 commercials that hooks up via the dock connector. The Apogee JAM. That one is $100 though.
So my question: is the iRig any good? Good sound, no latency issues? Or would the Apogee JAM be worth the extra $70?
