I think I will echo everyone else. A Platinum Preppy fine will be a great choice for a first time fountain pen user to decide whether a FP is right for them. $6 is not a big loss if it turns out you don't like it. It seals incredibly well and the pen can last a long time if you aren't too rough with it. It's definitely not a pen you can throw at the bottom of a backpack then toss the bag around (compare to the Lamy Safari which can take a good bit more abuse.).
The fine might be a touch scratchier since a Japanese F is usually more like a western EF. If you using a lot of garbage paper, definitely go with the EF. If you're working with paper that's more liquid ink friendly, maybe consider M for a slightly smoother experience.
Definitely buy a bunch of samples and a blunt tipped needle to fill the cartridge that comes with it in that order. If you aren't sure about 100% committing to FPs in that order, fill the rest of your cart for free shipping with stuff you could use otherwise. In terms of paper, I would say Rhodia and Clairefontaine are decent budget friendly paper. I am told Clairefontaine is dirt cheap in France. If you're in the UK, I'm also told Optik paper from Oxford is widely available for a good price there. Maybe consider some pens or pencils if the retailer has them.
Just a note, I'm not American or familiar with how professional standards organizations work in the US and I just quickly skimmed the committee's report, so this is all broad strokes.
What the article missed is that the committee recommended that Clark's punishment include Clark having to prove he is fit to practice law before Clark can be readmitted after the two year suspension, not an automatic reinstatement after two years has elapsed. In my opinion, this is a very serious omission on the part of the CNN writer that makes the recommendation sound lighter than it actually is.
If the disciplinary committee's recommendation is implemented in full, Clark needs to demonstrate to the satisfaction of the state's professional standards organization that he understands how badly he behaved as a lawyer, why he was punished as a result, and how he must behave in the future to meet the professional standards of a licensed lawyer. If the professional standards board members in the future are extremely strict and set an unreachable bar for Clark (which, in my opinion, would not be surprising given the international coverage of this entire disaster), this could essentially be a permanent loss of license.
How strict the professional standards organization would interpret "fitness to practice" in two year's time or the correctness of the disciplinary board's finding that Clark's behaviour didn't rise to the same level as Giuliani's (partially because Clark wasn't filing lawsuits over this matter) thus warranting a lighter punishment is up for debate. The less cynical and more optimistic side of me interprets this as a permanent loss in practice with a crack in the door that is the size of one atom if Clark can prove with absolute certainty he turned things around and spends his waking hours repenting for his misdeeds, is now an absolutely flawless example of how an ethical lawyer should behave, and uses any spare moment he has rescuing all the abandoned puppies and kittens in the world and finding them amazing forever homes. Realistically? Who knows. Two years is long enough that people forget and won't be outraged if the organization's requirements are low.
