They’re few and far between. The Romy brake alone went for $190 a month or so ago on GB in a penny auction. Earlier in the summer both the FSB/Brake went for upwards of $600 in a penny auction on GB. Then, recently someone parted out a kit and did a buy now for FSB alone for $250 (sold very quickly). There’s price data on the files, but it’s probably a bit stale by now (ranges between $300-450 for either the FSB alone or both).
