i did some serious scouring of the web and the eBay back in May when I purchased a Fuji Touring frame w/o a fork.
Ideally I wanted a 1" threaded Cr-Mo fork with double eyelets & Canti Brakes. The range of choices was pretty surprisingly wide, but I was unable to really even come close to what I wanted.
Dimension makes a bunch of replacement forks both in Hi-Ten and Cr-Mo steel; Threaded & Threadless.
Here's one for caliper brakes
