These get used a lot around here:

[h=1]Sunlite 27" x 1-1/4" Econo Fork Threaded length 3-15/16", 1" OD, Chrome, Non-Canti[/h]
If you scroll down the linked Amazon page, you'll see a buncha other
Sunlite forks in various configurations and sizes. They are not as good
as a lot of the original equipment, but they are pretty good forks for the price.

Mostly, I think it's probably a little heavier than your original fork.

I forget if your bike was set up for 27 or 700c, but I think they make both.

Here's the Cromolly version:
