I wouldn't touch Pensacola Diesel right now ... too many guys are walking horror stories about them, from what I read on the forums.
Strictly second-hand, but some of the stories are from guys I trust.
Have you tried Mid-West Fuel Injection?
Kennedy has new ones for $1195.
SSDiesel has rebuilts for under $600
Just some ideas. You might also call Henry at Creatures of the Night performance; his website doesn't list them, but he might be able to give you an idea or two...
