Assuming the heaters are in working order I think you got yourself a bargain . Bdial has covered pretty much all you need to know, but it's not a Quad - those have four heated slots. I think this type, which is three heated slots plus a wash, was called an RA4 and as the name implies they were designed for RA4 colour printing. I have a Quad which I've used for RA4 and Ilfochrome in the past, but I use it just for monochrome these days. There's no need to upgrade the heaters, the old design works perfectly well. If you don't have the "floating lids" a trip to a plumbers' merchant to pick up some plastic water pipe will sort that out. That's what Nova uses. If you email Nova you'll find them very helpful and able to advise what else you might need to get the most from the unit. It'll work fine for b+w, the built-in wash slot is ideal for RC papers.
