Exactly this. I started with a Lamy Al-Star and it's a nice, robust little pen for pretty cheap. Aluminum, so it can take being thrown around. My girlfriend recently started using the Safari and it's a good pen too.

My main "workhorse" pen is the Lamy Studio. Heavier than the Al-Star, a slightly grippy coating, better balance when "posted" (putting the cap on the end of the pen while writing). Also a bit thicker, which suits my personal preference.

This thread at SA is a pretty good primer for fountain pens and ink: http://forums.somethingawful.com/showthread.php?threadid=324...

I have a few other cheap chinese fountain pens that I mess around with, but mostly stick to my Studio.

Edit: Bonus points to owning a semi-nice fountain pen: you'll never lose a pen again. I religiously keep mine in my pocket because, damnit, I spent a lot of money on this pen! No more losing your 20 cent Bics and frantically trying to find a new writing implement.

Plus inks are fun to buy and experiment with :3

I can second the Lamy Safari suggestion. I found the Safari to be extremely reliable: always starts right away (even after weeks of not writing), never leaking (even in planes and or if I shake it), and needing very little pressure to write.

It might not be the smoothest or the prettiest for its price, it's stiff as a nail but its reliability made it an everyday writer for me.

I'll second the Varsity pens. I've bought, used up, and lost several of the Varsity pens. At $3/each, it's still less than having bought the Lamy pen mentioned above (which, btw, is considered an excellent starting pen), and in the process I've been able to write with a fountain pen for about a year. I like it a lot. One down side is that Varsity pens have ink that is not waterproof, and now that I live where it rains, I need something that lasts better.

Also, most notebooks or pads of paper in the office will absorb fountain pen ink like a 5 year old drinks chocolate milk, which makes your writing look terrible. The fountain pen forums linked above, and many blogs, have reviews about various types of paper. I found that I __really__ like the feel of the Staples sugar-cane paper. It feels nicer to write on than anything other than drafting vellum, so far, and is not very expensive. The notebooks are spiral-bound, but you can also buy it in reams, I believe.

I also tried another disposable fountain pen from The Other Brand (I forget the name?), and it seemed roughly similar to the Varsity. The clip on the cap was less flexible, though, and broke. I wouldn't have that problem with a more expensive pen, I imagine.
