With the dollar so weak now and the unlikelihood that Fender will offer the lefty Jaguar basses in the states anytime soon, these may be the only options, at least for appearance.
According to the description, it's an alder body with a maple neck/rosewood board, same specs as the real Jaguars. Without all the Jaguar switches, it looks like all other specs are standard Jazz, i.e. the PUP sizes, etc. so I think it's basically a Jazz bass with a Jaguar body (which may or may not be an improvement, having never heard the Jaguar basses, I can't comment on how they sound).
I stand corrected: the description says the PUPS are 3-5/8 x 3/4", which is the same size as the neck PUP on a standard J. Which means if you wanted to replace them you'd need TWO neck J PUPs of the same dimension, since the bridge PUP on a standard J is bigger (3/3/4 x 3/4" I believe).
