I collect fountain pens and have about 120 ( really ! )
I have a Mont Blanc Meisterstuck, which was very expensive but it really isn't worth all that money. If you are going to treat yourself, than look on Ebay for a Parker 51 or 61. These are easily the best pens that Parker ever produced and it was a sad day when they finally stopped making them.
But the good news is that they made millions of them ! I have found this on ebay today for you ::

Another good place to try for modern pens is Cultpens. I cannot recommend this mail order company in Devon highly enough ::

Another good make is Pilot. They make the Capless fountain pen, which is unique as it has a retractable nib. Pilot, Pelikan and others makes sold by cultpens are as good as any fountain pen can possibly be, and all are better than a Mont Blanc.
If you would like and more help or assistance to choose, please don't hesitate to ask. I wouldn't call myself an expert but I have picked up loads of info over the years ! By the way, I would still go for a Parker 51.
( just found this :::: the chalk marks were put on by Parker, so this has never been used ::::

Well worth the money for a new pen in all but name.
