It might be hard to find the same one again, though sometimes popular hybrids have cyclical availability so this one might pop up again at vendors in the future.
Oncidium Sharry Baby is very similar in terms of flower shape (and size?) and it nicely fragrant. That one tends to never go out of fashion, and could be a suitable alternative for you.
