I thought about peppermints, but I've read one too many threads about them not working, or peppermints taking a liking to some softies after they're done with the aptasia.
Some other people suggested that when you get a peppermint, you should not feed the tank, or feed very lightly, so that they work up an appetite. Either way, I think berghia is the safer, and more guaranteed choice.
If nobody has any locally, then I might just go the peppermint route... It'll certainly be cheaper.
