Appears 90's model -- Cannondale did use 1" steerers on some models into the mid-90s. It's a good frame, very light. Group is probably junk, ask what model (e.g. SM-xxx or whatver). Looks like alum fork so it'll have a STIFF ride. Would make a good urban bike. And it is a Cannondale. I'd pay $100 for it, no prob. 200$ is high but not crazy if great condition.
It looks to be a 1990's with the decal on the top tube and rapidfire shifters. Which is good as they came w/ Crmo forks in varing degrees of quality depending on the line. Components either SunTour XCM or Shimano Deore again depending on level.
