I live in Halifax, Nova Scotia - east coast of Canada. They both only have the one power supply. From my research, the Omega still has replacement parts as they still make enlargers. The Nikor is somewhat of a "classic", but quite older. Not sure about the heads. I got them both for really cheap. 100$ for all the equipment needed for developing and printing in excellent condition.


EDIT; just saw that you're from Canada...sorry about the Geography lesson!
