In recent years the only one I have seen and really liked is, 'The Reflecting Skin'. Some of the older ones from Dario Argento are awesome if you are into baroque, atmosperic chillers such as 'Susperia'. Early in his career Roman Polanski made some good ones like 'Repulsion', 'The Tenant', and 'Rosemary's Baby'. 'Last House on the Left' from Wes Craven is good if you like a nasty revenge plot heaped with human degradation. If you like gorefests, Lucio Fulci makes stomach turners and I think he is still producing them. I don't know much about newer ones as I lost interest in that genre in the early 90's.
