I'm in the UK. They're not common, but you do occasionally see them. I have one that I mostly use because I was taught to write in the italic style [0] of cursive, so mine has an Italic squared-off nib. I don't use it every day, however.

It cost me about £40, uses cartridges, and still manages to leak (blue, washable) ink on my fingers.
