I guess a good question here would be "what's 'reasonably priced'?"

I was looking around a possible fork options recently, and a good LBS cited ~$170 for a good production fork in Tange Prestige (from Soma? Surly? I don't recall, though Soma can go as low as $120-40 for Tange Infinity offerings - not Columbus, I know, and maybe not as nice as you'd like), and more like $300-400 for a Columbus fork from Marinoni (custom). The latter quote is similar to what you'd expect to pay for a custom from, say, Davidson in Seattle ($400 list price). Hopefully others are not too horrified to hear that I went with a Kestrel EMS 1" threaded carbon unit myself, at a mere 90 for one that'd never been ridden. For your application, almost certainly not the direction you'd go! Might be worth looking out for a used one (perhaps repaint to your preferred color to match), or considering a production fork?

I'm definitely interested in hearing suggestions as to what might be the best available deals on high quality road forks...
