Is this the last time we see the Ferengi till Peak Performance?
Hadn't noticed that huge gap before.
I'm glad they decided to give the species another go and that we eventually got the DS9 interpretation.
I'm guessing they were saved from completely vanishing by Peak Performance
being a very cheap episode that reused all its models from stock, and they were about the only old ship baddies that were competent enough to pose some threat (so, no Pakleds) but not a major enough villain for it to see unlikely the ruse at the end would work.
