Chypre is my favourite genre. There are still good ones to be had, often cheaply, amongst the reformulations of classics from the 70's and 80's.
Along with the aforementioned "Knowing" and "Miss Dior Original", I would also suggest the following: "Paloma Picasso / Mon Parfum", "Jean-Louis Scherrer", EL's "Private Collection", "Caleche" (the current EDT is supposedly closer to the original formula than the SDP, which is a simplified version), Patou's "1000", "Balmain de Balmain", "Miss Balmain", Paco Rabanne "La Nuit" - actually the list goes on. If you haven't smelled the originals you may not be so disappointed with the reformulations.
Cryptic is right about the 'modern' chypres. It seems that anything with a vetiver/patchouli base is now labelled a chypre, though some of these do smell great in their own right like "Lumiere Noire pour femme".
Two recent chypres that actually smell like they have oakmoss bases are "Bottega Veneta" (designer) and "Tarantella" by Tommi Sooni (niche). The latter is a gorgeously smooth green chypre that I would love to own if it weren't so pricey and had a tad more oomph.
