I have a Metropolitan, got it for $13 from Amazon.
This is a bit of an old post, I've already grown my collection somewhat. Aside from Pilot MR, I have a couple of FPR Himalaya and a Pelikan M200 Smoky Quartz SE.
And next I'm going for a Sailor 1911L. After buying the pens above and playing with some other pens, it seems for now I prefer Japanese. Pelikan was a huge disappointment, but seems to be just a dud, waiting for a replacement to arrive, hopefully it'll write better, as the originally received one writes much worse than a nail, I actually tried, I got an iron nail from my toolbox, dipped it in ink and it is much more reliable and pleasurable experience than the Pelikan I received :D
