Go with the Pelikan! The M800 pen is a wonderful all-around pen with a smooth nib,....

good ink flow, and an understated presentation. The piston fill mechanism is always a delight to use. I much prefer the piston fill to cartridges for ink quantity as well as the satisfaction accruing from operation of a well-engineered mechanism.

The Parker Sonnet, previously mentioned, is another sweet writing pen on a smaller scale. It seems to be overlooked by many but is quite pleasurable to use (but does utilize a cartridge/convertor filling system--the convertor being preferable as it mimics the piston-fill). The Sonnet Cisele is a great choice. The nib has some flex as well. And the price is right.

Good luck with your foray into the world of Fountain Pens.
