The frame holders in the extractor appears to have rust as does the upper lip. Check everything that would come in contact with the honey for rust well. If they don't have rust $400 to $500 is generous. If they do have rust, the more the lower the price. It's not fun getting rid of rust. This also assumes everything works properly, and you've got the time to clean up thoroughly. Contactme_11 is right, the hive bodies are a bonus.
