The bonus with Pings is that they have nice flowers like orchids! Plus, you can usually get pings for under ~$30 (USD), unless it's a special cultivar and/or hybrid.
A lot will actually breakdown pollen from other plants or even smaller plants that get stuck on their leaves, as well as bugs.
Pings are stupid easy to propagate from leaf pullings. If you get them from other hobbyists they're even less expensive.
