The Pod will do great for you if you want to have several different sounds that do not sound good. Really the Pod is awful, even the Vox Tone lab has made great improvements so its not awful, its just not any good.
saying the Pod can emulate a real amp is like saying you have been to Italy because you went to the Venetian Hotel in Las Vegas. They sound nothing like the amps they claim to emulate and they sound just plain bad regardless.
The biggest problem with all the amp emulators though is that they will make everything thing else on the records sound worse. Your drums, vocals, keys, acoustics etc will all sound worse because you used the Pod for guitars.
