I'm using 10€ Waterman I bought 15 years ago and life would feel different if I ever lose it. The price of ink in Japanese was always a bother to me, so I hoarded cartridges wherever I traveled home. I got a Parker at Christmas once but never really used it because of the feel of it plus the very expensive price of ink; also way too heavy.
