Unfortunately The amount of darkroom equipment in Rio seems to be pretty light(from comments here) Sooooooo, if it's clean it's worth what you're willing to pay.
In the Chicago area there was a computer controlled Durst 6X9 advertised for a long while. It started at $900. (enlarger only) and when I contacted the owner he was willing to sell it for $150. with one lens. I think he's still got it.
Beseler 23C's are advertised for between $40.00 and some unrealistically at $250. plus. Some without accessories, some with.
FWIW I think in thirty-five years in the business I've only seen one Fuji enlarger.
Hope this helps a bit.
