Hello Everyone, I am thinking of buying a modern Duofold set, FP, BP & MP, for regular use. Since modern Duofolds are not exactly inexpensive, even second-hand, I'd appreciate feedback from owners prior to purchase. It would be good to know if the modern Duofold is a reliable writer and how well does Parker support it? Also, are the MP and BP mechanisms well built and sufficiently reliable for regular long-term use? Are there any specific models or production years to avoid? All comments, pro and con, and links to additional info are greatly appreciated. Thanks in advance. Akhil
