Unfortunately people getting out of Balls tend to say whatever is necessary to sell them. I learned this the hard way from a deal with Tom Crutchfield.
However this is not always the case, but still I would trust your feelings and research over what the breeder says, if you are not 100% sure that it's a Super you may want to pass.
Being in a area so close to so many great reptile expos you definitely would not have a hard time finding another Lesser Super Pastel.
