The Fuji Regis was built in Sept emebr 1985, so there is a good possibility that was actually a 1986 model. I don't have any pricing info on the Regis for these years but models with Valite tubing were selling for as low as $230 US. Given that your Regis has lower grade tubing, it was lalmost certainly under $200.

Based on the tubing the Corsaro would be mid to late 1980s and a least on step up from the Fuji. Knowing the makes and models of the major components would be a help. Pics would be even better.
