Umberto Dei is an old, established Italian marque. If you visit small towns in central and northern Italy you will see many of them in use as primary transportation. They cater to the high-end market now, but are built to truly old-school specifications, e.g. rod brakes, all steel frame and racks, mudguards, etc. The $595 price on the eBay auction seems reasonable compared to the price a new Umberto Dei would cost in Europe.
