Red Lamy Safari
Lamy Safari is available in several colors at a very affordable price ($30). While being an inexpensive pen, it's got a bunch of pros:
And even though it's quite superb and a great first fountain pen to have, there are a few things that some people don't like about the Lamy Safari.
It's large - when posted (cap on back of pen) it can be too large for some people;
Plastic can get stained - especially white or yellow pens;
Grip is annoying for some people because of its angle;
Nibs run wide - too wide for some people;
Moreover, they're inconsistent. Same size nibs can write differently than another. Once in a while, you can get a scratchy nib.
