How good is Gameshark2?

[DeliveratorTitan]

What's your opinion for Gameshark2? I don't have one but I want to know how good is it.

I REALLY like mine... it adds a lot of fun to old games that you may have stopped playing by adding new things

Does anyone know where to get a good deal on one of these?
