So, I've been a fountain pen user for many years now. I have Lamy, Pelikan and Pilot pens. I'm looking to get my first Mont Blanc. Preferably a 149 or 146. However, I have some questions about this brand.
1) New ones are too expensive for me so I'll have to buy used. What are some reputable sellers where I can have a reasonable assurance that the pen is authentic and not counterfeit?
2) Any older pen is fine with me, but is there a sweet spot for vintage pens in terms of quality vs. price? I don't want to go over $400 US.
3) Are the vintage 149s/146s considered better made than more recent ones?
Thanks for any and all help.
