I think it should be the same fate for Sarcochilus fitzgeraldii. I found two additional growers where the price was in range, but one had very limited stock and the other wanted a minimum order of $50 + $4 handling fee per plant + shipping (I think that's probably a bit excessive). Plus, there's no indication on either if the plants are blooming size.
Polystachya paniculata can be found at Paramount for $28-30 nfs. That's the best I got for that one though.

I found a grower in the EU for Sophronitis acuensis
