It's a tough sell these days. I don't think you'll find anyone willing to pay money for darkroom gear, when so many are having a hard time giving it away. There ARE folks looking to find enlargers and darkroom equipment, but they seem to be few and far between, and they seem to have figured out that if they are patient and look hard enough they will find what they need for free. I used to work at B&H selling lighting, large format cameras and lenses, and darkroom stuff. I few weeks ago I was talking to a friend who still works there and I asked him if they still sell many enlargers and darkroom equipment. He laughed and said he thinks I probably sold the last enlarger they sold. (I left there almost 14 years ago.)
That said, I have an Omega D5500 chassis sitting unused I'd love to send to a good home if anyone is interested. Come take it away and use it.
