Nope. I'm really happy with this one. However, if I were to get an amph in the future it would probably not be a Jet City, not because they are bad, but because they no longer are associated with Mike Soldano. Quite frankly, his designs are what drew me to this in the first place. Having said that, I have no intention on getting a new amph unless the "magic smoke" would ever come out of this one.
