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:

• Cheap - for such a well made pen, the price is very reasonable;
• Replaceable nibs - $10 and very simple to replace;
• Easy to flush and refill - change color ink whenever you need;
• See through ink window - lets you know when ink is running low;
• Durable plastic available in different colors;
• Very firm nib - no flex - great for drawing;
• Nice grip - the handwriting is better when you can hold the pen securely.

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.
