I've been collecting fountain pens for a little while now (couple months) and I've been going crazy for them. Started out with a Metro in F, was kinda unhappy with the fineness and capacity and ink leaking into the cap (still a great pen) and eventually upgraded to a TWSBI 580AL, anodized to Rose, in F. I like the Jowo nibs much more than the Pilot nibs - lot more smoother and broader. Now, I have a LAMY AL-STAR in Charged Green on the way (caught it on the 50% sale and it was already another 50% off, so I ended up getting it for roughly $13 all in.)
I own a few inks, Noodler's Purple Wampum and Walnut, but I don't use them because they're ill-behaved in my 580AL on cheap paper. It's a shame too, they're pretty. I also have a bottle of Rohrer & Klingner's Scabiosa, which is absolutely wonderful and works on any paper, even getting a lot of shading out of it. Beautiful lilac.
