I think $1400 is reasonable to offer. If you do the quick math, a show pickup saves ~$50 on shipping, and then the other $150 is basically 10% off. Offer to pay cash or cashiers check, or some other manner that doesn't cost them a processing fee (3% lost on PayPal). If they decline or counter, just be ready with whether or not you still want her, and let them know one way or the other.
