You could just get a Pilot Prera demonstrator model already fitted with a CM (Calligraphy Medium) nib at the factory; it will come with a Pilot (proprietary) converter included in the retail package.
(Prera models that are opaque do not come with included converters, and CM nibs are not an option offered with those.)
I've seen those in at least one bricks-and-mortar shop in Sydney – specifically, Kinokuniya in The Galeries Victoria – so they aren't impossible to get locally. However, I could order one directly from Japan, and (have to) pay for international shipping by EMS service, yet still come out on top expense-wise; no way such a pen should be selling for $81.
Or you could buy Pilot Plumix pens with the same type of nib (which are in fact interchangeable between the Prera, MR, Kakuno, 78G, Plumix and Penmanship models). Amazon sells them, at more reasonable prices that what I've seen on eBay for the same products.
But, in either case, to answer your question: Pilot is the brand of pen you're after.
You could, of course, opt to try a Lamy pen with an Italic nib instead; you can buy those nibs as separate retail products, and just fit them onto your Lamy Safari, Al-Star, Logo, CP1, etc. yourself; it's really easy to do. Or go all out and buy yourself an Aurora pen fitted with a factory Italic nib.
