The guy selling Titan frames on Ebay has full-chrome Tange forks in his ebay store for $20. You'll have to get it cut down and threaded (unless you'e going threadless) but I'd bet you can get that done even in NYC for $20 or so; with shipping, I think you'd come out under 50.

There very well might be cheaper options - but not bad for NOS.
