Nikon d1 Is it still worth it?

Is the nikon D1 still worth it and does it look pro or Ugly

Not if you're asking the question.

What is the cost of it?

The D1 does not look much different than a D4

If your goal is to "look" like a pro, then you have a problem. There's more to looking like a pro than just owning a pro camera. You have to have a wealth of knowledge unless you want to embarrass yourself when hanging with real pros

Ugliness of a camera does not affect picture taking ability. If the D1 you are eying is still working perfectly and you can still find batteries and chargers for it then yes, it's worth it. IF you don't know how to use a dSLR properly then no, don't get it.
