Appears to be a circa 1986/1987 model, if so original price $325-$400 US. Nice recreational/sports model, about 23-24 lbs in that size, Tange #2 main tubes. Stays and forks could be CrMo or Mangalloy depending on year, the decal looks like it could be Mangalloy. Shimano Light Action SIS rear derailleur.
I'm always leery about dents. Hard to say without seeing it in person or a very good pic. Sounds like it's worth the drive, if the market is as hot as you infer.
