I have to recomend Naarika also but if you want somthing special then i can heartily recoment the Fountain Pen Emporium
My mum asked me what i would want for my 40th bithday, something special i could keep, a watch was out as i have so many and she does not have that much money, so i found a nice waterman from 1935 and she drove (only lives 30 min away) out there and bought it for me, it is absolutly stunning, real history and in its original service box. The bussines is ran by an old guy in his 70s who knows his stuff.
