Looks like you have an eighties Bianchi, similar to a couple I have owned in the past.
The bicycle is of Asian origin, not Italian. For the most part, it is well made but does not qualify as well crafted, unless robots are now considered to be crafty.
Though I have built up a few of these bicycles, I have ridden them little. The rides I have taken offered decent ride quality, but nothing truly memorable. That said, please keep in mind that I compare all bicycle to all of those that I have purposely tested. It is tough to match the ride quality of a Cyclops, or Marinoni, or Miele, all Canadian made works of well crafted bicycles.
For a bit of a better look at a bike very similar to the one starting this thread, have a look at
this one that has also been converted for Single Speed use...
Value - how much is it worth to you? How much will it sell for? One of the those above went for close to $600, one for closer to $250 and one didn't sell yet.
