Having had the pleasure of crewing on Fitz's boat, his top up here IMHO at a quality builder would come in around $3800 new. Maybe more...it folds.
A lot of thought, planning, and execution went into it...and easy access/entry too. And as Fitz said...built like a brick chithouse.
As Matt advised, add an upper station, they get expensive. Another $1800 easily...wheel, all controls.
Hopefishing has found a nice used top with upper station at a great price. If you can find something similar to his, or Fitz's (will be in Florida) it's worth the ride down there...IF you have a good aluminum fab shop nearby to make adjustments.
Take some measurements, and give Jake a call at Marine Connection Liquidators. Great folks, easy to deal with...and their prices are right:
