This still seems to be the best source of 1879, although if a >4.1 EPA grind is available direct purchase is better.

As for Romantic Notions, players with base Persuasive too low can upconvert Honey profitably. Unfortunately Honey isn't very accessible either, but at 170 *modified* Persuasive using the Freeloading Artist from your lab will allow a usable >12 RN/action. That caps out at 21 RN/action for 292 Modified though, so Mrs. Chapmans is superior outside a small window of good items and mediocre base stat.
