FWIW a Richard Sachs fork sold on eBay a few weeks ago for $400 or so. Or you can buy an RS fork crown and have someone (why not Richard?) put together a fork for you. I've been looking for a 55-56cm Ricahrd Sachs for a year or so. Those I see listed seem to fall into a couple of categories: 1) pristine with a price to go with it, 2) rough "barn/estate find" with an inflated price, 3) used up, worn out with many miles in need of restoration, often still with a big price tag.
