Any recommendations for an extreme macro lens to use on a bellows?
Working distance is not as much of an issue for this, I'm planning to
use it on an optical bench/bellows setup so as long as the lens doesn't
run into the subject I'd actually prefer a shorter working distance.

I picked up an old Spiratone 35mm f/3.5 bellows lens, supposedly it's
actually just an enlarger lens... T-mount... and it doesn't really hold
up to extreme magnifications like 1:8 shown here:

I've read Bjørn Rørslett's take on this and he recommends some very
expensive & rare short focal length lenses for this application:

One possiblity there is the olympus 38mm f/2.8 although it's probably
near impossible to find. There is one on ebay.ca in French, located in
Australia...

I'm shooting with a Nikon D700 & D200 so the Canon 60mm MP-E isn't an
option. Maybe I should be looking at microscope objectives?

I use a Reverse mounted 40mm F2.8 @ F5.6 Schneider Componon HM
Enlarger Lens for extreme macro work. I fit it to a bellows which is
attached to a precision adjustable platform and use stacking to expand
the very limited depth of field at these magnification. I sometime
also add extension tubes.

Here are a few of examples.
