Here is a pic of an old Nishiki I fixed up for my daughter. I picked it up at a yard sale for $10. Hand-built the wheels using some NOS Fuji gold and silver rims, and landed the really sweet old Shimano 600 groupo off eBay. Including paint, which I also did myself, I have less than $100 invested. And, if it gets the daughter riding, it's $100 well spent!
Couldn't pass up those beautiful lugs...this was a fun project, anxious to take on another one!
