As to the old printers, I had a 7500 for years. The problem with that model is that the carts have an old-style connection to the printer that puts a syringe needle type printer male end through a rubber cart female valve. They are not meant to be reused; they'll leak.
So, unless someone is using a CIS type system, I don't recommend going back as far as the 7500. The 7600 was the first modern coupling that allows reliable re-use.
That said, with the old 7500 and its large dots (not a problem with Eb6-Y 2%) was the only printer I had that could print (on slightly brightened papers and with Eb. v.1) a 100% carbon image where the Lab B never got above 0 -- very cool in at least two respects.

Thanks, Paul. I ended up going Eboni VT in the 7600, and the big prints are coming out beautifully. I decided I wouldn't be printing that many glossy prints, so the clogging potential with a not-heavily-used 7600 using the glossy config wouldn't be worth the ongoing hassles. And I can print a pretty decent B&W glossy on my new p600 if I really need one.
A general comment on repurposing old 24" or larger Epson printers to use B&W inksets -By replacing dampers and running Eb base through the head of my badly clogged 7600 (hadn't been used in many years), plus some gentle Windex syringe flushing, I was able to get it back up and running beautifully. If folks see old long-out-of-use printers cheap or free on local classifieds, give it a shot - you could get a top notch archival large format printer running for little $$$'s...
